Abstract
Scanning signal lines and video signal lines are provided in a matrix on the surface of one of a pair of glass substrates between which liquid crystal is filled. In each pixel area, thin film transistor is provided corresponding to each of cross points of the scanning signal lines and video signal lines. A reference signal line is provided across adjacent pixel areas, and reference electrodes are provided on one side of the reference signal line and extend in a comb-like form into each pixel area. A display electrode having a comb-like shape is provided such that it meshes with the reference electrodes. A light interception layer 111 having a width greater than that of display electrode and reference electrode is formed so as to overlap both of the electrode with an insulation film being interposed therebetween. Leakage of light from around sides of the display electrode and reference electrode is prevented even if liquid crystal molecules are inclined by an electric field produced by a voltage applied between the display electrode and reference electrode.
