Abstract:
A reflective liquid crystal display device comprising:first and second substrates opposed to each other; a liquid crystal layer sandwiched between the first and second substrates, the liquid crystal layer including a polymer-dispersed liquid crystal containing a liquid crystal and a liquid crystalline polymer; a transparent electrode interposed between the first substrate and liquid crystal layer; a quarter-wave plate interposed between the liquid crystal layer and second substrate; a reflective electrode interposed between the quarter-wave plate and second insulating substrate; and a polarizer disposed on the opposite side of the first substrate from the liquid crystal layer; wherein the liquid crystal and the liquid crystalline polymer are twisted in molecule alignment so as to have a twist angle X represented by X=(45Â°+90Â° n)Â±10Â° (n=0 or a positive integer).
