In the present embodiment, the black matrix 210 includes a plurality of first openings 211, second openings 212, and third openings 213 distributed in an array. The first opening 211, the second opening 212, and the third opening 213 may have the same shape or different shapes. The first opening 211, the second opening 212, and the third opening 213 are different in size.
In the embodiment, the sizes of the first opening 211, the second opening 212 and the third opening 213 are set to be different, so that the main maximum diffraction angles of the lights with different colors passing through different openings are the same, and the secondary maximum diffraction angles of the lights with different colors are the same, so that the peaks of the lights with different colors are superposed with each other, thereby forming white light and improving the color separation problem.
