Abstract: PROBLEM TO BE SOLVED: To increase a display region of a liquid crystal display device used for a portable terminal device such as a portable computer and to make the portable terminal device using the liquid crystal display device thin. SOLUTION: The liquid crystal display device and a peripheral device are fixed to each other using a screw 200 by arranging a mounting hole 160 on a side face of the liquid crystal display device without forming a screw forming part on the front surface. Thereby the weight of the liquid crystal display device is decreased and is suited for the portable terminal device because the area ratio of the display region of the liquid crystal display device is improved and the thickness is reduced compared with conventional dimensions and further a mounting part for the mounting hole is made unnecessary.

Abstract: PROBLEM TO BE SOLVED: To provide the panel driving method of a dot inversion system in which voltage to be supplied to the liquid crystal cell is made constant. SOLUTION: In this liquid crystal panel driving method of the dot inversion system and its driving device, liquid crystal cells which are adjacent with each other and to which video signals having the same polarity are to be inputted receive the input of the video signals during periods different with each other. That is, the liquid crystal cell to which a first video signal is to be inputted receives a video signal longer by a prescribed time than the period when the video signal is inputted to the liquid crystal cell to which a second video signal is to be inputted so that the same voltage can be supplied to respective liquid crystal cells. As a result, the same voltage is supplied to the liquid crystal cells which are adjacent with each other and to which video signals having the same polarity are to be inputted.

Abstract: PROBLEM TO BE SOLVED: To manufacture a liquid crystal panel by minimizing the parasitic capacitance between the source and drain electrodes, in a new structure design of the shapes of the source and the drain electrodes, and minimizing variation in parasitic capacitance. SOLUTION: For an array substrate for a liquid crystal display device, parasitic capacitance caused by overlap between gate and data electrodes of a switching element on an array substrate is minimized to reduce the variation in the parasitic capacitance. The gate electrode in the lower part of drain electrode is etched to form a switching element to minimize the parasitic capacitance, to prevent the overlap between the part of the drain electrode and the gate electrode so that the parasitic capacitance is minimized. The overlapped part between the gate electrode and the drain electrode is formed symmetrically, to mutually compensate the overlapped, area even when miss align is caused at the overlapped part of the gate electrode and the drain electrode, so that the variation in parasitic capacitance and the liquid crystal display with superior images can be manufactured.
