Abstract

The invention is a liquid crystal display (LCD), comprising a first substrate, a second one, many pixel electrodes, a first oriented film and a liquid crystal layer, where the second substrate is opposite to and parallel with the first one, these pixel electrodes are arranged on the first substrate in an matrix form, the first oriented film is arranged on the pixel electrodes or the second substrate and provided with a first oriented region and a second oriented region, the liquid crystal layer is arranged between the two substrates and provided with many liquid crystal molecules; besides, the liquid crystal molecules corresponding to the first oriented region have a first preinclined angle and those corresponding to the second oriented region have a second preinclined angle, where the second preinclined angle is greater than the first one.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device in which liquid crystal molecules located in two orientation regions relative to an orientation film have different pretilt angles. Background technique [0002] Liquid crystal display devices are widely used due to their advantages of low radiation and light, thin and small volume. The thin film transistor (TFT) liquid crystal display device is very popular in high-end electronic products because of its high brightness and large viewing angle. [0003] A traditional liquid crystal display device consists of a thin film transistor substrate and a color filter substrate sandwiching a liquid crystal layer through a sealant. The color filter substrate includes at least an upper substrate, a common electrode, a color filter sheet (color filter, CF), black matrix (black matrix, BM) and upper alignment film, while the thin film transistor substrate inc...
