Abstract: The display device includes a backlight module, a light switching layer and a color filtering layer. The backlight module includes a plurality of micro light emitting units, wherein each of the micro light emitting units is independently controlled to emit a light. The light switching layer is located above the backlight module, wherein the light switching layer controls whether a light emitted from each of the micro light emitting unit of the backlight module penetrates the light switching layer or not. The color filtering layer is located above the light switching layer, wherein the color filtering layer includes a plurality of quantum dots with different colors, a color of the light emitted by each of the micro light emitting unit is converted by each of the quantum dots, and a plurality of sub-pixel units with different colors are formed by each of the quantum dots.
