Claim 2:
3. The liquid crystal display panel according to claim 2, wherein the sub-pixels comprise the red sub-pixel, the green sub-pixel, and the blue sub-pixel, and the sub-grating in each of the sub-pixels comprises a plurality of layers with a same thickness; and
wherein emission wavelengths of the sub-gratings in the red sub-pixel area, the green sub-pixel area, and the blue sub-pixel area are controlled according to the Bragg equation: 2d sin θ=nλ, where d is a thickness of the layers of each of the sub-gratings, θ is an incident angle of incident light, n is a refractive index of the layers of each of the sub-gratings, λ is an emission wavelength, and the emission light wavelength of each of the sub-gratings is controlled by adjusting the thickness of the layers of each of the sub-gratings, the incident angle of the incident light, and the refractive index of the layers of each of the sub-gratings.
