Abstract:
A liquid crystal display device comprising:a first substrate;a second substrate;a liquid crystal layer interposed between the first substrate and the second substrate;a first polarizer provided on a surface of the first substrate which is opposite the liquid crystal layer;a second polarizer provided on a surface of the second substrate which is opposite the liquid crystal layer;a first phase compensation element provided between the first polarizer and the liquid crystal layer; anda second phase compensation element provided between the second polarizer and the liquid crystal layer,wherein a plurality of pixel areas are provided for display,wherein the first substrate includes at least one transmissive electrode, and the second substrate includes a reflective electrode region and a transmissive electrode region in correspondence with each of the plurality of pixel areaswherein each of the plurality of pixel areas has a reflective region for performing display using reflected light and a transmissive region for performing display using transmitted light, and the reflective electrode region defines the reflective region and the transmissive electrode region defines the transmissive region; andwherein the liquid crystal layer has a retardation of .alpha. when a molecular axis of liquid crystal molecules in the liquid crystal layer is almost vertical with respect to the surface of the first and second substrates, and the first phase compensation element has a retardation which fulfills .lambda./4-.alpha. condition.
