A display device is a device for displaying a screen such as a character, a number, a symbol, a picture, or an image formed by combining at least two of the character, the number, the symbol, and the picture. When the display device works, driving voltages are applied to the Thin Film Transistor Array Substrate and the Color Filter Substrate respectively, and the rotation direction of the liquid crystal molecules between the two substrates is controlled, so that backlight provided by a backlight module of the display device is refracted, and a picture is displayed.
The color of the display device is usually realized by a Color Filter (CF), the conventional color filter includes a red photoresist, a green photoresist and a blue photoresist arranged in a certain order, the red photoresist, the green photoresist and the blue photoresist are separated by a Black Matrix (BM), when the backlight provided by the backlight module passes through the red photoresist, the green photoresist and the blue photoresist, only the light of the corresponding red waveband, the light of the corresponding green waveband and the light of the corresponding blue waveband can be transmitted, and the color display of the display device is realized.
