Liquid crystal display device with a pretilt angle of liquid crystal molecules

Abstract

An LCD device (10) includes a first substrate (22), a second substrate (21), and a liquid crystal layer (23) having liquid crystal molecules interposed between the first and second substrates. A pretilt angle of liquid crystal molecules is in the range from 0° to 15°. A first upper retardation film (521) is disposed at an outer surface of the first substrate. Preferably, the first upper retardation film is a quarter-wave plate. A first lower retardation film (511) is disposed at an outer surface of the second substrate. Preferably, the first lower retardation film is a quarter-wave plate. This helps ensure that the LCD device provides a good quality display. In addition, the alignment and the pretilt angle of the liquid crystal molecules in the liquid crystal layer are such that the liquid crystal molecules are homogeneously aligned when this is needed, and can be twisted in a very short time.
