Reflection type liquid crystal display device

A reflection type liquid crystal display device including a panel, a polarizing plate, and a +E,fra 1/4+EE wavelength plate, with the polarizing plate and the +E,fra 1/4+EE wavelength plate being placed upon the panel. The panel includes a transparent first substrate disposed at the external light incoming side; a second substrate opposing the first substrate, with the first substrate and the second substrate being put together so as to be separated by a predetermined distance; nematic liquid crystals kept in the gap between the substrates, with the molecules thereof having a twisted orientation; and an electrode, formed at both of the substrates, for applying a voltage to the nematic liquid crystals. When a voltage is not applied, the orientation of the molecules of the nematic liquid crystals is maintained, so that the nematic liquid crystals act together as a +E,fra 1/4+EE wavelength layer. Therefore, the nematic liquid crystals cooperate with the polarizing plate and the +E,fra 1/4+EE wavelength plate in order to pass external light and produce a white display. On the other hand, when a voltage is applied, the orientation of the molecules of the nematic liquid crystals is changed to a substantially vertical orientation, so that the nematic liquid crystals lose their ability to act together as a +E,fra 1/4+EE wavelength layer.
