Abstract: A grating structure includes slit regions (4) and light blocking regions (5) that are alternately distributed in a first direction. The slit regions (4) and the light blocking regions (5) extend in a second direction, and the first direction is perpendicular to the second direction. The grating structure further includes two electrode plates (10, 20) disposed oppositely, and a plurality of support columns (3) disposed between the two electrode plates (10, 20) and supporting them. At least two of the support columns (3) are spaced apart in the first direction are arranged in each of the slit regions (4).
