Abstract

The invention discloses a display substrate, a manufacturing method thereof, a display panel and a display device. The display substrate comprises a bottom plate. A light filtering layer is arranged on the bottom plate and comprises a light-transmitting area. The light-transmitting area corresponds to sub-pixels. A first photonic crystal structure is arranged on the light-transmitting area and used for transmitting light rays of preset wavelength. The display substrate presents corresponding colors after the photonic crystal structure transmits the light rays of preset wavelength, and therefore manufacturing cost is reduced, and the manufacturing process is shortened. In addition, by means of the technical scheme, the transmittance of light rays is increased, and energy consumption is lowered.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate and a preparation method thereof, a display panel and a display device. Background technique [0002] The existing color filter substrate is a color filter pattern formed by three kinds of color filter resins of red, green and blue through exposure and development. The switching device on the array substrate controls the passage of light. Appears in corresponding colors. However, since the color filter substrate is formed by three exposures of the color filter mask, the production cost of the existing color filter substrate is relatively high, and the production process is relatively long. Contents of the invention [0003] In order to solve the above problems, the present invention provides a display substrate and its preparation method, a display panel and a display device, which are used to solve the problems that the existing color filter subst...
