Abstract
A reflective liquid crystal display apparatus with pixels includes a first electrode substrate, a second electrode substrate and a liquid crystal layer. The first electrode substrate includes a polymer layer having plural protrusions or depressions arranged randomly formed on a glass substrate, and a reflective layer, color filters, transparent electrodes, and an alignment layer formed and laminated sequentially on the polymer layer. The second electrode substrate, includes transparent electrodes and an alignment layer formed and laminated on a glass substrate, and arranged so that the alignment layer faces the alignment layer on the first electrode substrate. The liquid crystal layer is formed by filling a liquid crystal composition into an interval between the first and second electrode substrates. Portions of the reflective layer corresponding to the portions of each pixel other than apertures of each pixel are colored black.
