Method for improving viewing angle of liquid crystal display and liquid crystal display

Abstract

The invention provides a method for improving the viewing angle of a liquid crystal display and a liquid crystal display. The method comprises the steps that: a black shading unit is manufactured at a position on a second surface plane of a glass substrate which is opposite to a black light resistor; and a second surface plane is over against a first surface plane, and the black light resistor and the black shading unit are respectively arranged on both sides of the glass substrate. The method for improving the viewing angle of the liquid crystal display or the liquid crystal display can improve the viewing angle of the liquid crystal display, and increase the aperture opening rate; and in addition, the invention can also improve the pair-group tolerance error of a one-fourth phase difference plate and the liquid crystal display, so that the pair-group defective rate is reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a method for improving the viewing angle of a liquid crystal display and a liquid crystal display. Background technique [0002] As we all know, in a 3D liquid crystal display, the light emitted by the polarizer on the color filter side of the liquid crystal display is linearly polarized light. Vertical linearly polarized light. After the two linearly polarized lights pass through the 1 / 4 wavelength retardation plate with an included angle of 45 degrees, they will form left-handed circularly polarized light and right-handed circularly polarized light. Left-handed circularly polarized light and right-handed circularly polarized light pass through the 1 / 4 wavelength retardation plate on the glasses to form linearly polarized light, and then pass through the polarizer on the glasses to reach the left and right eyes respectively. A piece of glass and a polarizer (total thickn...

Problems solved by technology

Although this method can improve the aperture ratio, it needs to add a black light-shielding layer on the 1 / 4 wavelength retardation plate

Especially in the current market, the thin-film type 1 / 4 wavelength retardation film provided by many manufacturers is to directly make a quarter retardation film on the film material. If a black light-shielding layer is added, an additional alignment Exposure, and the steps of developing on the film, easily lead to poor stability of film thickness
