Embodiment 1

[0035] In Embodiment 1 of the present invention, the plane structure diagram of a pixel unit of the color filter is as follows image 3 As shown, the color filter is mainly composed of a substrate (not shown in the figure, such as glass, quartz or organic matter, etc.), black matrix 2 (opaque film layer, such as resin film layer, etc.), each color unit ( The red unit 3, the blue unit 4 and the green unit 5 are composed of colored film layers, such as RGB resin film layers, etc.) are arranged in the black matrix 2, the protective layer (not shown in the figure) and the spacer 7 at intervals Composition; wherein, each color unit is provided with an opening.

[0036] The preparation method of the above-mentioned color filter in embodiment 1 comprises steps:

[0037] A black matrix layer and a color unit layer are formed on the substrate, and the color unit layers are arranged at intervals in the black matrix layer;

[0038] Openings are formed on the color unit layer through a ...

Embodiment 2

[0041] see Figure 4-7 , in embodiment 2 of the present invention, actually covers multiple implementation modes, and its difference with embodiment 1 mainly lies in:

[0042] 1. The shape, size, size and quantity of the openings on the color unit layer can be set according to actual needs.

[0043] specifically, Figure 4 An embodiment in which the openings are parallel slits in the vertical direction is given; Figure 5 An embodiment in which the opening is an obliquely upward parallel slit is given; Figure 6 An embodiment of two sets of parallel slit openings is given, the two sets of parallel slit openings are distributed axisymmetrically with respect to the x-axis or y-axis on the color unit layer, and the x-axis or y-axis Parallel or perpendicular to the boundary 2' in the black matrix (this way is relative to Figure 4 , 5 The area of ​​the opening is increased, so the light transmittance can be further increased); Figure 7 Embodiments with multiple point openin...

Abstract

The invention relates to the technical field of display and provides a color filter, a display device and a preparation method of color filter. The color filter comprises a substrate, and a black matrix layer and colored unit layers, which are arranged on the substrate, the colored unit layers are arranged in the black matrix layer at intervals, and the color filter is characterized in that openings are arranged on the colored unit layers. The color filter has a simple structure, and certain openings are formed on the colored unit layers so that more incident light can penetrate through the color filter, thereby not only meeting the demand of the color filter on color, but also greatly improving the transmittance of the color filter. Meanwhile, according to the invention, the conventional preparation technique is not improved greatly, the color filter with a specially-shaped opening can be obtained just by a special mask design, the current production line is not changed at all, and color filters with better performance can be obtained on the condition that the equipment cost is not increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color filter, a display device and a preparation method of the color filter. Background technique [0002] LCD (Liquid Crystal Display, liquid crystal display) devices have the advantages of light weight, thin thickness, low power consumption and low radiation, and have been widely used in information technology, multimedia technology and other fields, and gradually become the mainstream of various display devices. With the development of display technology, liquid crystal displays with high transmittance, large size, low power consumption and low cost have become the direction of future development. [0003] To achieve color display on the liquid crystal panel, a color filter (CF, Color Filter) is one of the important components, and its performance has an important influence on the effect of the liquid crystal display. Since color filters determine the color display quality...
