Problems solved by technology

However, due to the limitations of the current color filter layer preparation process, defective products often occur when using this method. To a certain extent, but can not be reduced indefinitely, resulting in the light transmittance can not reach the ideal situation
[0005] It can be seen that the problem of low light transmittance of liquid crystal display devices cannot be completely solved by reducing the thickness of the color filter layer.

Embodiment 1

[0037] This embodiment provides a color filter substrate, such as figure 1 As shown, it includes a substrate 1, a black matrix 7 and color filter layers 2 of different colors. The black matrix 7 is arranged on the substrate 1, and the sub-pixel area 6 is formed on the substrate 1 not covered by the black matrix 7. The color filter layer 2 is arranged In the sub-pixel area 6 , the color filter layer 2 includes a plurality of high-brightness transparent parts arranged at intervals, and the light transmittance of the high-brightness transparent parts is greater than that of other parts of the color filter layer 2 .

[0038] The highlight light-transmitting part is a through hole 21 opened in the color filter layer 2 , the through hole 21 is uniformly arranged in the color filter layer 2 , and the center line of the through hole 21 along its height direction is perpendicular to the substrate 1 .

[0039] In addition, a flat layer 3 is also provided on the color filter substrate, t...

Embodiment 2

[0058] This embodiment provides a color filter substrate, which is different from Embodiment 1, such as Figure 4 As shown, the bright light-transmitting part is a blind hole 22 opened in the color filter layer 2, the blind hole 22 is evenly arranged in the color filter layer 2, and the center line of the blind hole 22 along its height direction is perpendicular to the substrate 1 .

[0059] Compared with Embodiment 1, the blind hole 22 does not penetrate the entire color filter layer 2 compared with the through hole, that is, the opening end of the blind hole 22 is set on the upper surface of the color filter layer 2, and its bottom ends inside the color filter layer 2 . The cross-sectional shape and opening size of the blind hole 22 and its distribution in the color filter layer 2 are the same as those in Embodiment 1, and the other structures and materials of the color filter substrate provided in this embodiment are also the same as in Embodiment 1. Here, I won't repeat ...

Embodiment 3

[0070] This embodiment provides a display device, including the color filter substrate provided by any one of the above embodiments.

[0071] Since the display device adopts the color filter substrate described in the above-mentioned embodiments, the transmittance of light in the display device is improved, thereby improving the display effect of the display device.

Abstract

The invention provides a colorful-film substrate, a colorful-film substrate manufacturing method and a display device. The colorful-film substrate comprises a substrate body, a black matrix and a colorful film layer with different colors, wherein the black matrix is arranged on the substrate body, a sub pixel area is formed on the part, not covered by the black matrix, of the substrate, the colorful film layer is arranged in the sub pixel area and comprises a plurality of highlighted light-transmitting portions which are arranged at intervals, and the light transmitting rate of the highlighted light-transmitting portions is larger than the light transmitting rate of other portions of the colorful film layer. The colorful-film substrate manufacturing method comprises the step of forming the colorful film layer through a picture composition technology, wherein the highlighted light-transmitting portions are arranged in the colorful film layer. The light transmitting rate of the colorful-film substrate is improved through lowering of color resistance of the highlighted light-transmitting portions, and meanwhile the display effect of the display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a color filter substrate, a method for preparing the color filter substrate, and a display device. Background technique [0002] A liquid crystal display device (LCD: Liquid Crystal Display) has become a mainstream product among flat panel display devices due to its small size, low power consumption, and no radiation. The liquid crystal display device includes an array substrate for the cell, a color filter substrate, and a backlight source. The color filter substrate is an important part of the liquid crystal display device and is also a key component that affects the display effect. [0003] Usually, the color filter substrate in the liquid crystal display device includes three primary color film layers (Resin) of red, green and blue (RGB). On the one hand, the light from the backlight can realize the colorization of the image after passing through the color filter l...
