ABSTRACT:
The invention provides a semi-transparent reflective liquid crystal display device in which bright display, high contrast, and less viewing-angle dependency are possible in a transmission mode. In the liquid crystal display device according to the present invention, a polarizing plate can be disposed on the upper side of a liquid crystal cell in which a semi-transparent reflective layer is formed on a lower substrate and the thickness of a liquid crystal layer in a transmissive display region can be made to be different from the thickness of a liquid crystal layer in a reflective display region by a layer-thickness adjusting layer. A uniaxially stretched phase difference film can be interposed between the polarizing plate and the liquid crystal cell, and a liquid crystal film fixed in nematic hybrid alignment can be interposed between the phase difference film and the liquid crystal cell. A polarizing plate can be disposed on the lower side of the liquid crystal cell, a uniaxially stretched phase difference film can be interposed between the polarizing plate and the liquid crystal cell, and a liquid crystal film fixed in nematic hybrid alignment can be interposed between the phase difference film 6 and the liquid crystal cell.
