摘要： A micro LED display device includes: a substrate; a plurality of micro light-emitting diodes disposed on the substrate; and a reflective layer and a black layer sequentially stacked on the substrate. The reflective layer and the black layer cover a surface of the substrate, wherein a top surface of the plurality of micro light-emitting diodes is exposed through the reflective layer and the black layer. A plurality of reflective banks and a plurality of black banks are sequentially disposed on the black layer and exposing the plurality of micro light-emitting diodes; and a color-conversion material covers the top surface of at least one of the plurality of micro light-emitting diodes. The color-conversion material is laterally disposed between the plurality of reflective banks. The reflective layer, the black layer, the plurality of reflective banks, and the plurality of black banks overlap each other in a display direction.
