Abstract

A liquid crystal display device includes first and second substrates and a vertically-aligned liquid crystal layer. The first substrate includes a pixel electrode and a first alignment film. The second substrate includes a counter electrode and a second alignment film. The first alignment film has, within each pixel, first and second pretilt regions that define first and second pretilt directions, respectively, that are antiparallel to each other. The second alignment film has, within each pixel, third and fourth pretilt regions that define third and fourth pretilt directions, respectively, that are antiparallel to each other. At least either a surface of the first substrate or a surface of the second substrate has a groove formed so as to overlap at least either a boundary between the first and second pretilt regions or a boundary between the third and fourth pretilt regions when seen from a direction normal to a display surface.
