Abstract:
A transflective liquid crystal display device comprising:an array substrate and a counter substrate; a liquid crystal layer sandwiched between the substrates; pixel electrodes located on a surface of the array substrate facing the liquid crystal layer, each of the pixel electrodes comprising an electrode for reflective display and an electrode for transmissive display; a counter electrode located on a surface of the counter substrate facing the liquid crystal layer; an alignment film covering the surface of each of the substrates facing the liquid crystal layer; and a color filter layer located on the counter substrate facing the electrode for reflective display; and a light source for irradiating the liquid crystal layer with colored light on a time division basis through the electrode for transmissive display, wherein the color filter layer comprises a cholesteric liquid crystal and a pair of electrodes for applying a voltage to the cholesteric liquid crystal.
