1. A liquid crystal display panel, comprising an array of pixel units, wherein each pixel unit comprises a plurality of sub-pixel units, wherein the liquid crystal display panel further comprises:
- a first substrate and a second substrate opposite to each other;
a liquid crystal layer as well as a pixel electrode layer and a common electrode layer for driving the liquid crystal layer between the first substrate and the second substrate; and
a waveguide grating between the liquid crystal layer and the first substrate, wherein the waveguide grating comprises a waveguide layer and a grating layer on a surface of the waveguide layer facing the liquid crystal layer, and the grating layer is in contact with the liquid crystal layer;
whereinthe pixel electrode layer comprises an array of pixel sub-electrodes insulated from each other, wherein each sub-pixel unit corresponds to a plurality of pixel sub-electrodes;
the grating layer comprises an array of grating units, wherein each grating unit comprises a plurality of grating sub-units, and each grating sub-unit corresponds to a pixel sub-electrode; and
a refractive index of each grating sub-unit is configured for allowing no light to be transmitted through a corresponding portion of liquid crystal when a first voltage is applied to a respective pixel sub-electrode, and for allowing light to be transmitted through a corresponding portion of liquid crystal with a predetermined grayscale when a second voltage is applied to a respective pixel sub-electrode, wherein the second voltage is different from the first voltage.
