Color Filter Substrate, Color Filter, Display Panel and Display Device

摘要

The invemtion discloses a color filter substrate. The color filter substrate includes a plurality of pixels arranged in an array, and each of the pixels at least includes a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel. The first sub-pixel is coated with a first color photoresist, the second sub-pixel is coated with a second color photoresist, and the third sub-pixel is coated with a third color photoresist. A photoresist of the fourth sub-pixel is formed by stacking any two of the first color photoresist, the second color photoresist and the third color photoresist. The present invention also provides a color filter, a display panel and a display device. They all are capable of increasing the color gamut, simplifying the production process, increasing productivity and reducing costs.
