ABSTRACT:
A liquid crystal display includes an element substrate, pixel electrodes and a common electrode that are formed on the element substrate, a counter substrate, a liquid crystal layer that is formed between the counter substrate and the element substrate, first and second polarizing plates that are provided on an emitting side of display light and an opposite side, respectively, and a retardation film that is provided in a reflective region to be disposed between the liquid crystal layer and the first polarizing plate. Each pixel has a transmissive region where transmissive display light is emitted and a reflective region where reflective display light is emitted. The retardation of the retardation film has smaller temperature dependency than the retardation of the liquid crystal layer.
