Claim 0:
1. A liquid crystal display panel, comprising a pixel area, and further comprising:
a reflective layer;
a glass substrate serving as a light guide plate, disposed on the reflective layer;
a grating structure disposed on the light guide plate and corresponding to the pixel area;
a planarization layer disposed on the grating structure; and
a thin-film transistor layer disposed on the planarization layer
wherein the pixel area comprises a red sub-pixel, a green sub-pixel, and a blue sub-pixel, the grating structure comprises a plurality of sub-gratings corresponding to the red sub-pixel, the green sub-pixel, and the blue sub-pixel one by one; and
film thicknesses and refractive indexes of the sub-gratings respectively corresponding to the red sub-pixel, the green sub-pixel, and the blue sub-pixel are different.
