Problems solved by technology
In the existing color filters, the transmission peak of the color-resist material is relatively wide, so the purity of the light emitted by the pixels is reduced. This color purity is limited, and it is difficult to meet the needs of users.

Abstract
The invention discloses a display panel and a display device. The display panel comprises a first substrate, a second substrate, first reflection structures, second reflection structures, pixels and color resistors. The first substrate is arranged on one side of a light emitting surface of the display panel, the second substrate and the first substrate are oppositely arranged, the first reflection structures are arranged on one side, close to the second substrate, of the first substrate, the plurality of pixels are arranged on one side, close to the first substrate, of the second substrate, and the first reflection structures are arranged between every two adjacent pixels; each pixel comprises a second reflection structure arranged on the second substrate, Bragg reflectors arranged on the corresponding second reflection structure, the color resistors are arranged between the first reflection structures and the Bragg reflectors, the Bragg reflectors have at least two types, and the Bragg reflectors of different types are used for reflecting light of different wave bands; the color resistors have at least two different colors, and the color resistors and the Bragg reflectors are correspondingly arranged. In this way, the color purity of the display device is improved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The display device has many advantages such as thin body, power saving, and no radiation, and has been widely used. Existing display devices mainly include liquid crystal display devices (Liquid Crystal Display, LCD) and organic electroluminescent display devices (Organic Light Emitting Display, OLED). [0003] The color of LCD is realized by color filter (CF, color filter). In the existing color filter, the transmission peak of the color-resist material is relatively wide, so the purity of the light emitted by the pixel is reduced, and the color purity is limited, which is difficult to meet the needs of users. [0004] Therefore, it is necessary to explore new technical solutions to improve the color purity of liquid crystal display devices. Contents of the invention [0005] The purpose of the p...
