Blue light blocking liquid crystal display

Abstract

The application provides a blue light prevention liquid crystal display, and belongs to the field of liquid crystal display. The liquid crystal display comprises a backlight module, an array substrate and a color film substrate. The array substrate is arranged between the backlight module and the color film substrate. The color film substrate comprises a black matrix configured to absorb light incident to the black matrix. At least one spacer is arranged between the array substrate and the color film substrate to support the array substrate and the color film substrate. At least one photosensitive resin grating is arranged on the radial outer side of the spacer. The photosensitive resin grating is configured to have a periodically changing refractive index distribution to guide blue light of a target wavelength band incident to the photosensitive resin grating at a target angle to the black matrix based on Bragg diffraction.
