Claim 8:
9. A method of manufacturing a liquid crystal display panel, wherein the liquid crystal display panel comprises a pixel area, and the method of manufacturing the liquid crystal display panel comprises the following steps:
providing a glass substrate configured to serve a light guide plate;
preparing a reflective layer on a side of the light guide plate;
preparing a grating structure on a side of the light guide plate away from the reflective layer, wherein a position of the grating structure corresponds to the pixel area, the pixel area comprises a red sub-pixel, a green sub-pixel, and a blue sub-pixel, and 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;
preparing a planarization layer on a side of the grating structure away from the light guide plate; and
preparing a thin-film transistor layer on a side of the planarization layer away from the light guide plate;
wherein 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.
