1. A liquid crystal display panel comprising:
a thin film transistor substrate;
a color filter substrate facing the thin film transistor substrate, the color filter substrate comprising a glass substrate, a black matrix on the glass substrate, and a color filter layer on the glass substrate; both the black matrix and the color filter layer being on a side of the glass substrate facing the thin film transistor substrate;
a liquid crystal layer between the color filter substrate and the thin film transistor substrate;
wherein a surface of the glass substrate defines a plurality of grooves having different depths; both the black matrix and the color filter layer are located in the plurality of grooves;
wherein a thickness of the liquid crystal layer maintains a same change trend as depths of the plurality of grooves; any two of the plurality of grooves have different depths and each of the plurality of grooves has a constant depth; the glass substrate comprises a first side and a second side opposite to the first side; depths of the plurality of grooves gradually increases in a direction from the first side towards the second side.
