Abstract: A micro LED display device includes a micro LED array, a light enhancing layer, a color filter and a polarizer. The micro LED array includes a plurality of micro LEDs, wherein each of the micro LEDs is independently controlled to emit a light. The light enhancing layer is located above the micro LED array, wherein the light enhancing layer includes a plurality of quantum dots. The color filter is located above the light enhancing layer, wherein properties of the light of each of the micro LEDs is converted by each of the quantum dots thereby projecting a plurality of sub-pixel units in the color filter. The polarizer is located above the color filter.
