Abstract:
1. A transflective liquid crystal display device comprising: a liquid crystal display panel, wherein the liquid crystal display panel includes a pair of substrates, a liquid crystal layer interposed between the pair of substrates, a plurality of sub-pixels, a transmissive unit and a reflective unit, the transmissive unit and the reflective unit being possessed by each of the plurality of sub-pixels, and a pixel electrode and an opposed electrode, the pixel electrode and the opposed electrode being formed on one of the pair of substrates and possessed by each of the plurality of sub-pixels, wherein the pixel electrode is shared by the transmissive unit as a first pixel electrode and shared by the reflective unit as a second pixel electrode in each of the plurality of sub-pixels, and wherein, assuming that a narrower angle of angles formed by an initial liquid crystal alignment direction of the liquid crystal layer and a projection direction of the first pixel electrode shared by the transmissive unit is θt and that a narrower angle of angles formed by the initial liquid crystal alignment direction of the liquid crystal layer and a projection direction of the second pixel electrode shared by the reflective unit is θr, a relation of θt >θr is satisfied when the liquid crystal layer is a positive-type liquid crystal and a relation of θr >θt is satisfied when the liquid crystal layer is a negative-type liquid crystal.
