Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a preparation method thereof, and a display device. Background technique [0002] The liquid crystal panel in TFT-LCD (Thin Film Transistor-Liquid Crystal Display, thin film transistor liquid crystal display device) is mainly composed of an array substrate, a color filter substrate and a liquid crystal layer between the array substrate and the color filter substrate. Two polarizers whose polarization directions are completely perpendicular are respectively arranged on the substrate. When the TFT-LCD is working, the light emitted by the backlight illuminates the array substrate, and the transmittance of the light through the liquid crystal layer and the color substrate is determined according to the image data input to the TFT-LCD. The display panel can display different colors according to different transmittances. Color grayscale, and display the im...

Problems solved by technology

The backlight source of TFT-LCD is white light, which is usually composed of three primary colors of red, green and blue. The white light becomes linearly polarized white light after passing through the polarizer on the array substrate side, and the linearly polarized light is polarized after passing through the liquid crystal layer. The direction is affected by the thickness of the liquid crystal layer and the deflection angle of the liquid crystal. Generally, the pixel electrodes or common electrodes corresponding to the red, green, and blue sub-pixel units in the LCD have the same structure and the same voltage, so that the red, green, and blue sub-pixel units The deflection angle of the liquid crystal is the same, so when the white light passes through the liquid crystal layer with the same liquid crystal thickness and the same liquid crystal deflection angle, because the polarization angles of the red, green and blue light that make up the white light are different, then these three kinds of light pass through the color film substrate The polarizer on the side makes the transmittance of the three kinds of light unequal. This phenomenon will lead to the unequal ratio of the light intensity of the outgoing light passing through the three sub-pixel units, and then make the color of the three outgoing lights mixed with white light. There is a color shift between the colors, and when the image is displayed, due to the influence of the color shift, there is a difference between the displayed image and the original image, which affects the display effect
