A display device includes a display panel, a backlight module, an optical sheet, and a polarizer. The display panel includes a plurality of first-color sub-pixels, a plurality of second-color sub-pixels, and a plurality of third-color sub-pixels. The backlight module includes a blue light source. The optical sheet includes a substrate, a plurality of transparent bumps, and a photo-excitation layer. The transparent bumps are overlapped with the third-color sub-pixels in a vertical projecting direction. The photo-excitation layer includes first photo-excitation regions which are overlapped with the first-color sub-pixels in the vertical projecting direction, and second photo-excitation regions which are overlapped with the second-color sub-pixels in the vertical projecting direction. Each of the first photo-excitation regions and the second photo-excitation regions has a plurality of first-color quantum dots and a plurality of second-color quantum dots. The polarizer is between the display panel and the optical sheet.
