A color filter substrate, a display panel, and a display device

Abstract

A color film substrate comprises a color resistor layer and multiple supporting spacers distributed in a dispersed mode. The color resistor layer comprises a color resistor array, the color resistor array comprises multiple color resistors arranged in an array mode, and the color resistors include red color resistors, green color resistors and blue color resistors; the supporting spacers are arranged in regions among the color resistors and include first supporting spacers, second supporting spacers and third supporting spacers. The color resistors closest to the first supporting spacers are the red color resistors, the color resistors closest to the second supporting spacers are the green color resistors, the color resistors closest to the third supporting spacers are the blue color resistors, and the number of the first supporting spacers is larger than that of the second supporting spacers. In this way, dark state brightness is reduced, and the purpose of increasing the contrast ratio is achieved; the phenomenon that the dark state is slightly red is weakened and not easily perceived by human eyes, and the taste of dark state pictures is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter substrate, a display panel and a display device. Background technique [0002] Liquid crystal display devices have the advantages of no radiation, thinness, and power saving, and have been widely used in various information, communication, and consumer electronics products. A liquid crystal display device generally includes a liquid crystal display panel. The liquid crystal display panel includes a color filter substrate and an array substrate arranged opposite to each other, and a liquid crystal layer arranged between the two substrates. In the liquid crystal display panel, the thickness of the above-mentioned liquid crystal layer is kept constant by using support spacers (PS) arranged between the color filter substrate and the array substrate. [0003] In order to arrange the liquid crystal molecules in the liquid crystal layer in a specific dire...

Problems solved by technology

Because the supporting spacer has a certain height, when the alignment film is rubbed and oriented by a rubbing alignment device, due to the blocking effect of the supporting spacer, a small part of the alignment film is formed in the area adjacent to the supporting spacer. The area cannot be rubbed, and the friction groove cannot be formed, which will cause the liquid crystal molecules in the small area to be disordered, resulting in light leakage, resulting in a decrease in the picture quality of the display device

[0004] In the prior art, there are two schemes for the distribution of the support spacers. The first scheme is: arranging a plurality of support spacers evenly, that is, the support spacers near the red, green and blue color resistance The quantity is equal, the disadvantage of this arrangement is serious light leakage in the dark state, high brightness in the dark state, and poor contrast

The second solution is: Since the human eye is very sensitive to green, green is the brightest visually compared to red and blue. Therefore, in order to reduce the brightness of the dark state, compared with the first solution, the color near the green color resistance is removed. The supporting spacer, this method does reduce the brightness of the dark state, but because red is visually brighter than blue, and the leaked light is not mixed with green components, this leads to a dark state. red, affect the visual effect
