Abstract

The invention discloses a photonic crystal, a color film substrate, a display panel and a display device and belongs to the technical field of display. A forbidden band of the photonic crystal comprises an visible waveband and defect layers are arranged in the photonic crystal. The photonic crystal comprises a red area, a green area and a blue area, the photonic crystal with a defect layer which corresponds to the red area is used for penetrating through red light, the photonic crystal with a defect layer which corresponds to the green area is used for penetrating through green light, and the photonic crystal with a defect layer which corresponds to the blue area is used for penetrating through blue light. The color film substrate and the display panel respectively comprise photonic crystal films formed by the photonic crystal. The display device comprises a display device which comprises photonic crystal films. The photonic crystal, the color film substrate, the display panel and the display device solve the technical problem that the display panel has low transmittance.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a photonic crystal, a color filter substrate, a display panel and a display device provided with the display panel. Background technique [0002] With the continuous development of display technologies, liquid crystal displays (Liquid Crystal Display, LCD) have occupied a dominant position in the field of flat panel displays. The backlight source in the existing liquid crystal display emits white light, which is divided into three colors of red, green and blue after being filtered by three-color color filters. [0003] In the process of realizing the present invention, the inventors found that the prior art has at least the following problems: white light is composed of light of different colors in different frequency bands, and after being filtered by a color filter, most of the light is Absorbed by the color film, only one color of light can pass through, so the e...
