Display device
A display device includes a display area, a pixel array, a display medium layer, and a color filter layer. The display area includes a plurality of sub-pixel regions, and each of the sub-pixel regions has a length and a width that are substantially the same. The pixel array corresponds to the display area in position. The display medium layer is located on the pixel array. The color filter layer includes a plurality of color resists. The color resists are arranged along a first direction and a second direction different from the first direction. Two adjacent color resists arranged along the first direction have different colors, two adjacent color resists arranged along the second direction have different colors, and adjacent two of the color resists are spaced apart from each other.
