Abstract
Each pixel has a reflection region to produce a display in reflection mode. The first substrate includes: a pixel electrode for each pixel; and a first vertical alignment film. The second substrate includes: an opposite electrode opposite the pixel electrodes; and a second vertical alignment film. Of the first and second vertical alignment films, only the second vertical alignment film exerts an alignment-regulating force that determines a pretilt angle. Each pixel electrode includes a plurality of subpixel electrodes. The opposite electrode has an opening in an area corresponding to one of four corners of at least one of the plurality of subpixel electrodes. Liquid crystal molecules in a thickness-wise middle portion of the liquid crystal layer on the subpixel electrode are oriented toward the opening.
