A liquid crystal display device includes an array substrate and a counter-substrate, a liquid crystal layer which is held between the array substrate and counter-substrate and includes a transmissive display part and a reflective display part which neighbor each other via a boundary, an alignment state of liquid crystal molecules in the liquid crystal layer being controlled by an application voltage from the array substrate and counter-substrate in the transmissive display part and the reflective display part, and control means for making an alignment direction of the liquid crystal molecules, which are present near the boundary in the reflective display part, substantially match an alignment direction of the liquid crystal molecules which are present near the boundary in the transmissive display part.

Liquid crystal display device

A first phase plate and a third phase plate, which constitute a polarizer structure, cooperate to impart a phase difference of a &#xbc; wavelength to linearly polarized light that emerges from a first polarizer plate. A second phase plate and a fourth phase plate cooperate to impart a phase difference of a &#xbc; wavelength to linearly polarized light that emerges from a second polarizer plate. Slow axes in planes of the first phase plate and the second phase plate are substantially parallel. A crossed-axes angle between slow axes in planes of the first phase plate and the third phase plate is 60&#xb0;, a crossed-axes angle between slow axes in planes of the second phase plate and the fourth phase plate is 60&#xb0;, and a crossed-axes angle between slow axes in planes of the third phase plate and fourth phase plate is 60&#xb0;.
