Abstract

The invention discloses a liquid crystal display. The liquid crystal display comprises a first polarizing film, a first substrate, a liquid crystal layer, a second substrate and a second polarizing film, and the first polarizing film has a first transmission axis; the first substrate has a first orientation parallel to the first transmission axis; the second substrate has a second orientation parallel to the first transmission axis; the second polarizing film has a second transmission axis vertical to the first transmission axis; incidence light from a backlight unit passes through the first polarizing film, first substrate, liquid crystal layer, second substrate and second polarizing film in sequence; the first substrate and second substrate comprise a plurality of dual-domain pixel electrodes. The optical density of the liquid crystal display is reduced without voltage, the visual angle is broad, the color difference is small, and the imaged picture is bright-colored.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display. Background technique [0002] In the traditional in-plane switching mode (IPS, In-Plane Switching) liquid crystal display or fringe field switching mode (FFS, Fringe Field Switching) liquid crystal display, there is a problem that the incident light from the backlight unit cannot be fully controlled when the display is dark. As a result, the brightness of the dark state increases and the contrast decreases. When the contrast decreases, the black and white picture contrast of the liquid crystal display is not clear enough, and the quality of the picture decreases, making it difficult to display bright images. Contents of the invention [0003] The invention provides a liquid crystal display to solve the above-mentioned technical problems of the liquid crystal display that the black and white picture contrast is not clear enough and the picture quality ...
