The present disclosure relates to a display device and a color filter. The color filter includes a dielectric layer and wire grid structures on the dielectric layer, each of the wire grid structures includes a first wire grid unit, a second wire grid unit, a third wire grid unit, and a fourth wire grid unit. The first wire grid unit, the second wire grid unit, the third wire grid unit, and the fourth wire grid unit respectively includes a plurality of wire grids spaced apart from each other. Grid-spaces of the first wire grid unit, the second wire grid unit, the third wire grid unit, and the fourth wire grid unit are different. With such configuration, the white CIE composited by the R sub-pixel, the G sub-pixel, and the B sub-pixel may be matched with the white CIE of the W sub-pixel. 1. A color filter , comprising:an dielectric layer and a wire grid structure array arranged on the dielectric layer, wherein the wire grid structure array comprises a plurality of wire grid structures, each of the wire grid structures comprises a first wire grid unit, a second wire grid unit, a third wire grid unit, and a fourth wire grid unit, and the first wire grid unit, the second wire grid unit, the third wire grid unit, and the fourth wire grid unit respectively comprises a plurality of wire grids spaced apart from each other, wherein grid-spaces of the first wire grid unit, the second wire grid unit, the third wire grid unit, and the fourth wire grid unit are different, and the first wire grid unit, the second wire grid unit, the third wire grid unit, and the fourth wire grid unit are configured to respectively filter incident light beams to obtain light beams of four different colors.2. The color filter as claimed in claim 1 , wherein the grid-spaces of the first wire grid unit claim 1 , the second wire grid unit claim 1 , and the third wire grid unit are configured to be gradually decreased in sequence.3. The color filter as claimed in claim 2 , wherein a cross-section of the ...
