WIPO Patent Application WO/2018/079411
Kind Code:
A1
Abstract:
A liquid crystal display device provided with a first and a second substrate, and a vertically aligned liquid crystal layer. The first substrate has pixel electrodes and a first alignment film. The second substrate has counter electrodes and a second alignment film. The first alignment film has, in each pixel, a first and a second pre-tilt region for defining pre-tilt directions that are anti-parallel with each other. The second alignment film has, in each pixel, a third and a fourth pre-tilt region for defining pre-tilt directions that are anti-parallel with each other. The surface of the first substrate and/or the surface of the second substrate has a groove formed so as to overlap with the boundary between the first and second pre-tilt regions and/or the boundary between the third and fourth pre-tilt regions when viewed from the normal direction of the display surface.
