Abstract: PROBLEM TO BE SOLVED: To arrange spacers only in the non-pixel regions within a display region and to prevent the spacers from being arranged in pixel regions. SOLUTION: Minus potential is impressed on a black mask 5 having apertures 7 (corresponding to the pixel regions) at prescribed points and plus potential is impressed on a common electrode 9 having apertures 12 (corresponding to the non-pixel regions) and apertures 11 (corresponding to sealing material forming regions) at prescribed points. The spacers 25 to which a plus charge is imparted are sprayed in this state on a common substrate 1. The spacers 25 are then sprayed only in the non-pixel regions and the sealing material forming region by electrical attraction force and electrical repulsive force. In such a case, the spacers 25 are coated with adhesive 24 and are, therefore, adhered to the sprayed positions. The sealing materials are formed only by the spacers 25 coated with the adhesives 24 sprayed to the sealing material forming regions.

Abstract: PROBLEM TO BE SOLVED: To uniformize the gap between two transparent substrates. SOLUTION: The lower base substrate 11 is provided with an extra area 13 around a rectangular transparent substrate formation area 12 for forming a single lower transparent substrate. In the transparent substrate formation area 12, a black matrix 14 is formed. In the extra area 13, a dummy black matrix 15 connected to the black matrix 14 is formed. In this case, even if electrostatical charging quantities are different by black matrixes 14 when static electricity is applied, electrostatic charges speedily move through dummy black matrixes 14, so that all the black matrixes 14 are held at the same potential. Consequently, spacers can be dispersed uniformly. Therefore, the gap between the two transparent substrates becomes uniform.

Abstract: PROBLEM TO BE SOLVED: To decrease the amts. of the spacers dislodging from the top of a substrate and to enhance the use efficiency of the spacers by electrifying the electrodes on the surface of the substrate to the polarity reverse from the polarity of the spacers, then spraying the spacers onto the substrate. SOLUTION: The substrate 22 for a liquid crystal display element is arranged horizontally on a transporting mechanism 8 by directing the surface formed with counter electrodes upward. The charges reverse from the polarity electrified to the spacers 25 are impressed on the counter electrodes of the substrate 22 by the discharge generated by a discharger 9 during the transportation of the substrate 22, by which the counter electrodes are electrified. The substrate 22 is transported through a carrying-in port 4 into a spraying chamber 1 and is fixed onto a stage 10. The spacers 25 housed in a housing box 3 are sprayed in the prescribed amt. toward the substrate 22 by gravity falling through a spraying nozzle 2. The attraction effect based on the electrification is generated between the sprayed spacers 25 and the substrate 22 and the falling spacers 25 are stably adhered onto the substrate 22 by the attraction effect.

Abstract: PROBLEM TO BE SOLVED: To furthermore uniform a cell gap in an active matrix type liquid crystal display device provided with thin film transistors(TRs) as switching elements. SOLUTION: The cell gap state of a pixel periphery part B is simulated to that of a pixel part A without forming the gate insulating films 21 of a thin film TRs on the whole upper surface of a thin film TR substrate 1, i.e., by removing the gate insulating films 21 from the pixel periphery part B as less as possible. Since the cell gap state of the pixel periphery part 13 can be simulated to that of the pixel part A, not only the furthermore uniformity of the cell gap but the high precision, etc., of the liquid crystal display device can be attained.

Abstract: PROBLEM TO BE SOLVED: To provide a device which can stably correct defective pixels even if a liquid crystal panel has a large pixel size and a narrow BM line width. SOLUTION: In a device defective pixels are inspected while photographing a light image of a liquid crystal panel 1 with a video camera 20 and moving it by an XY stage and a cell gap of a liquid crystal layer is widened by decreasing a pressure added to the liquid crystal panel 1 in the periphery of inspected defective pixels with suction of air at an opening 5a of a sucking plate 5. Furthermore, air bubbles are generated within the liquid crystal layer by irradiating defective pixels regions several times with a laser beam from a laser oscillator 22 and besides the defective pixels are corrected by melting and scattering component members of the defective pixels within the air bubbles.

Abstract: PROBLEM TO BE SOLVED: To execute the correction of a defective pixel with good accuracy and to improve a display grade by controlling the range of the air bubbles and splashing components generated by irradiation with a laser beam. SOLUTION: The pressure in a vacuum suction head 15 is reduced to bulge a transparent substrate 17 of the part corresponding to the defective pixel of a liquid crystal panel 10 toward the inside of a suction hole 16, by which the gap G between the transparent substrates 17 of the part corresponding to the defective pixel of the liquid crystal panel 10 is made larger than its peripheral part. When the part of the defective pixel within the bulged and deformed region is irradiated with the laser beam in this state, the air bubble 20 is generated in a liquid crystal layer 18. This air bubble 20 spreads nearly to a circular shape around the part where the gap G between the transparent substrates 17 is largest within the region where the gap G between the transparent substrates 17 is larger than the peripheral parts thereof. The size of the air bubble 20 and the range where the components 22 splash is limited and the execution of the correction of the defective pixel with the good accuracy is made possible and the display grade is improved.
