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 (SUB), and an end of the pixel electrode (PX) and the video signal line (DL) overlap each other. Over a second substrate (SUB), 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).
