Patent ID: 7474367

Claim:
A liquid crystal display device comprising: a liquid crystal layer interposed between two opposed substrates; a dot region having a transmissive display region and a reflective display region; a thickness of the liquid crystal layer in the transmissive display region being greater than the thickness in the reflective display region; a reflective layer provided at the reflective display region; and a retardation layer provided at the reflective display region of the liquid crystal layer side of one of the substrates, the retardation layer giving transmitted light a phase shift of about a quarter wavelength, and the thickness of the liquid crystal layer in the transmissive display regions being about twice as large as the thickness in the reflective display regions, so that with one of a voltage applied to the liquid crystal layer and no voltage applied to the liquid crystal layer, the phase shifts of the liquid crystal layer in the reflective display regions and the transmissive display regions being substantially zero, and with the other of a voltage applied to the liquid crystal layer and no voltage applied to the liquid crystal layer, the phase shifts of the liquid crystal layer in the reflective display regions and the transmissive display regions being about a quarter wavelength and a half wavelength, respectively.
