Abstract: A liquid crystal display device comprises a TFT substrate, a CF substrate, a liquid crystal with negative dielectric anisotropy filled between the substrates, a pixel electrode provided on the TFT substrate, and an auxiliary electrode formed around the pixel electrode. A slit for segmenting a pixel region into a plurality of sub-pixel regions is formed in the pixel electrode from the center portion of each pixel toward the periphery portion thereof. The auxiliary electrode has a transparent step film formed at a position corresponding to the slit of the pixel electrode in such a way as to overlie the auxiliary electrode. Molecules of the liquid crystal of each sub-pixel region are aligned toward center of the sub-pixel region from the circumference of the sub-pixel region by a horizontal electric filed applied between the pixel electrode and auxiliary electrode, and the shape of the end portion of the transparent step film.

Abstract: PROBLEM TO BE SOLVED: To further reduce the light leakage of a defective pixel on a liquid crystal display panel when physically destroying and correcting part of the defective pixel by irradiating it with a laser beam. SOLUTION: The arrow in the figure shows the irradiation patter of the laser beam. Almost all the periphery along with the peripheral of the defective pixel 12 and also the inside area thereof are uniformly irradiated so as not to cross anywhere in the from of so-called one-stroke writing from a radiation start point shown by a white circle on a little lower right side than the central part of a defective pixel 12 to a radiation end point shown by a black circle on a little lower left side than the central part of the defective pixel 12.

Abstract: PROBLEM TO BE SOLVED: To provide the spacer scattering device characterized by that the electrostatic charging quantity of spacers is controlled. SOLUTION: The spacer scattering device charges spacers 1 electrostatically on the path from a spacer supply means 2 to a nozzle 4 having its injection hole directed into a housing 10 through the interaction with its piping 3 or nozzle 4 accompanying the passage of the spacers 1. The electrostatic charging of the spacers 1 is controlled by selecting the material of the piping member of one of the piping 3 and nozzle 4. The control is based upon a comparison between the piping member of the piping or nozzle 4 and the spacer material on a frictional electrostatic charging series and the spacers 1 can be charged electrostatically to a desired potential.

Abstract: PROBLEM TO BE SOLVED: To improve the aperture ratio of pixels without decreasing the light transmissivity of a liquid crystal panel in a liquid crystal display device. SOLUTION: A liquid crystal panel 20 of a liquid crystal display device consists of a transparent substrate 2 where TFTs 4 are formed and a transparent substrate 3 where a common electrode 10 is formed. On the transparent substrate 2 on the side of the TFTs 4, color filters (r), (g) and (b) are formed on a gate insulating film 8 and drain lines 7 and pixel electrodes 5 are formed thereupon. Namely, the drain lines 7 and the pixel electrodes 5 are laminated and formed at different positions in the insulated state that the color filters (r), (g) and (b) are held between them. Therefore, the side edge part of the pixel electrode 5 and the side edge part of the drain line 7 can be put in the state that the both are insulated from each other and laminated up and down. Consequently, a light leak between the pixel electrodes 5 and the drain lines 7 can be prevented without newly forming a light shield film.

Abstract: PROBLEM TO BE SOLVED: To determine whether a liquid crystal display element has a display defect or its color filter has a defect by obtaining a waveform of a difference signal between a signal of sequentially detecting emitted light from each array of pixels of the element and a delay signal wherein the detection signal is delayed by a predetermined period. SOLUTION: A liquid crystal display element 10 is supported on a movable holder 20, and while the display element 10 is moved at a constant speed in its lengthwise direction by movement of the movable holder 20, light from a light source 22 placed at a predetermined position is shed to the display element 10 for detecting emitted light from pixels in each array (R, G, E) by a photo sensor 23. A defect determiner 25 delays a detection signal by a predetermined period in a delay signal generation part 26 based on the detection signal. One of the detection signal and the delay signal is subtracted from the other in a subtraction part 27, and a difference signal of a waveform corresponding to the difference is output. A defect determination part 28 determines whether a display defect exists from the waveform of the difference signal. The determination is done against short-circuit, breakage and mixture of a foreign material. An inspection driving circuit 21 is temporarily connected for driving the element 10.

Abstract: PURPOSE:To obtain a high contrast by properly keeping the gap between substrates and improving the numerical aperture of a picture element part and eliminating spot defects. CONSTITUTION:A spacer 19 having a prescribed particle size is uniformly scattered on either of upper and lower glass substrates 12 and 13 and both substrates are stuck to each other with a seal material between them to constitute a liquid crystal cell, and ultrasonic oscillation is given to liquid crystal charged in this liquid crystal cell. Spacer particles whose size is equal to the gap width of non-picture element parts 17 whose gap width is larger than that of picture element parts 18 are moved to the side of non-picture element parts 17 by this ultrasonic oscillation. Thus, the gap adjustment of picture element parts 18 is properly performed, and the numerical aperture is improved because the spacer doesn't exist in picture element parts, and spot defects or the like are prevented, thereby obtaining a high contrast.
