ABSTRACT:
A reflective liquid crystal display apparatus has a liquid crystal display part composed of at least a liquid crystal layer and a pair of polarizers holding the liquid crystal layer therebetween, for display of bright and dark states in a mode of transmitting and shielding external light in a direction approximately normal to a display plane, and a reflecting part for reflecting the external light which has been transmitted through the liquid crystal display part. The liquid crystal display part has a property where it can transmit external light in a designated direction other than in a direction approximately normal to the display plane even in a mode of shielding the external light, and the reflecting part reflects the external light received in the designated direction so as to transmit the external light once again through the liquid crystal display part in a direction approximately normal to the display plane.
