Problems solved by technology

However, due to the bonding layer 3, polarizer 4, etc. between the patterned retardation film 5 and the black matrix 2, the distance can generally reach 0.5mm-0.7mm, so that some light rays with a large inclination angle will break away from the corresponding pixel of the pixel unit. range of phase retarders, causing crosstalk
In other words, the viewing angle that can be displayed normally is generally only within the angle range of 2°-8° from the vertical line on the surface of the liquid crystal panel. If the angle of inclination is too large, generally exceeding 10°, the normally displayed 3D image will not be visible.

Embodiment 1

[0028] image 3 It is a schematic structural diagram of a color filter substrate provided in Embodiment 1 of the present invention. The color filter substrate includes a base substrate 1, and a patterned retardation film 5 is provided on the side of the base substrate 1 facing away from the array substrate. The patterned retardation film 5 is composed of multiple It is composed of phase retarders arranged in block array form. Each phase retarder in the pattern retardation film 5 corresponds to the pixel unit respectively, so as to respectively present the left-eye image and the right-eye image; a first black matrix 21 is arranged between the base substrate 1 and the pattern retardation film 5, and Each first black matrix 21 corresponds to the adjacency between each block of phase retarders.

[0029] The technical solution of this embodiment is applicable to a liquid crystal display that uses a patterned retardation film 5 to realize three-dimensional display. Such as image...

Embodiment 2

[0033] Figure 4 It is a schematic structural diagram of the color filter substrate provided in Embodiment 2 of the present invention, and the array substrate 10 is also shown in the schematic diagram. This embodiment can be based on Embodiment 1, the difference is that: the side of the base substrate 1 facing the array substrate 10 is also provided with a second black matrix 22, that is, the second black matrix 22 is arranged on the base substrate 1 facing the array substrate 10 Inside, a liquid crystal layer (not shown in the figure) is filled between the array substrate 10 and the color filter substrate.

[0034] In the technical solution of this embodiment, the first black matrix 21 and the second black matrix 22 can jointly realize the function of blocking the light of adjacent pixel units, such as Figure 5 As shown, the arrangement of the first black matrix 21 and the second black matrix 22 widens the range in which the black matrix can continuously block light.

Embodiment 3

[0037] Figure 6 It is a flow chart of a method for manufacturing a color filter substrate provided in Embodiment 3 of the present invention, and the method includes the following steps:

[0038] Step 610, forming a pattern of a first black matrix on the first side of the base substrate away from the array substrate;

[0039] Step 620, forming a patterned retardation film on the first side of the base substrate where the first black matrix is ​​formed, each phase retarder in the patterned retardation film corresponds to the pixel unit, and each first black matrix corresponds to each block phase The adjacency between delayers.

[0040] The technical solution of this embodiment can be used to prepare the color filter substrate provided by the present invention, which can improve the viewing angle of the display by shortening the distance between the black matrix and the phase retarder.

Abstract

An embodiment of the disclosed technology provides a color filter substrate with a plurality of pixel units, comprising: a base substrate, a patterned phase retarder film disposed at a first side of the base substrate, and each of phase retarders of the patterned phase retarder film respectively corresponds to each of pixel units; and a first black matrix disposed between the base substrate and the patterned phase retarder film, where each portion of the first black matrix corresponds to a border of two adjacent phase retarders.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a color filter substrate, a manufacturing method thereof, and a 3D liquid crystal display. Background technique [0002] A liquid crystal display is a commonly used flat panel display at present, and a thin film transistor liquid crystal display (ThinFilm Transistor Liquid Crystal Display, TFT-LCD for short) is a mainstream product in the liquid crystal display. At present, three-dimensional (3D) display is an important development trend of LCD, and there are various realization principles, one of which is to realize 3D display by setting a patterned retarder film (Patterned Retarder Film). [0003] The liquid crystal panel of the liquid crystal display includes an array substrate and a color filter substrate arranged in opposite boxes, and a liquid crystal layer is filled between them. Polarizers are arranged on both sides of the liquid crystal panel, and images are presented...
