Claim Text:
1. A liquid crystal display device comprising: a first substrate including a transmissive pixel electrode which is disposed in a transmissive display area and includes a main pixel electrode with a strip shape extending in a second direction, a reflective pixel electrode with a planar plate shape which is disposed in a reflective display area, and a shield electrode which is disposed in the transmissive display area; a second substrate including a common electrode which includes a plate electrode with a planar plate shape opposed to the reflective pixel electrode, the common electrode having the same potential as the shield electrode; a liquid crystal layer including liquid crystal molecules held between the first substrate and the second substrate, the liquid crystal layer being configured to have a less thickness in the reflective display area than in the transmissive display area, to impart a phase difference of ¼ wavelength to light passing at an OFF time in the reflective display area, and to impart no phase difference to light passing at an ON time in the reflective display area; a first polarizer disposed on an outside of the first substrate and having a first polarization axis; a second polarizer disposed on an outside of the second substrate and having a second polarization axis which is perpendicular to the first polarization axis; and a retardation plate disposed between the second polarizer and the second substrate in the reflective display area, and configured to impart a phase difference of ½ wavelength.
