Abstract: In a liquid crystal display device small in the size and having a narrow frame, an alignment film can be coated by ink jet printing, by coating a rapidly drying peripheral alignment film 109 in the shape of a frame to a TFT substrate 100 having a display region having pixel electrode 107 and a peripheral region thereof by ink jet printing, and then coating a display region alignment film 108 drying slower but excellent in the leveling effect by ink jet printing. While the display region alignment film 108 dries slowly, since the peripheral alignment film 109 formed to the periphery functions as a stopper, the shape of the alignment film can be defined accurately, thereby enabling to prevent lowering of the adhesion of the seal member 20 under the effect of the alignment film. This can be applied also on the side of the counter substrate 200.

Abstract: Light leakage between pixel electrodes over a video signal line in a TN-type liquid crystal display device in which a dot inversion driving is applied with a three o'clock viewing angle is prevented. Pixel electrodes (PX) are formed on both sides of a video signal line (DL) of a first substrate (SUB1), and an end of the pixel electrode (PX) and the video signal line (DL) overlap each other. Over a second substrate (SUB2), a black matrix (BM) is formed in a portion corresponding to the video signal line (DL). By shifting the black matrix BM and the video signal line DL to the left with respect to a gap G between the pixel electrodes PX, it is possible to prevent light leakage caused by a disclination line (DS) which occurs by a horizontal electric field between pixel electrodes (PX).
