Claim 0:
1. A micro LED display device, comprising:
a substrate;
a plurality of micro light-emitting diodes disposed on the substrate;
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 each micro light-emitting diode is exposed through the reflective layer and the black layer, and a sidewall of each micro light-emitting diode is covered by the reflective layer and the black layer;
a plurality of reflective banks and a plurality of black banks sequentially disposed on the black layer and exposing the top surface of the plurality of micro light-emitting diodes, wherein the reflective layer, the black layer, the plurality of reflective banks, and the plurality of black banks overlap each other in a display direction, wherein the black layer further comprises concave portions located between the plurality of micro light-emitting diodes, and the plurality of reflective banks sit on the concave portions; and
a color-conversion material covering the top surface of at least one of the plurality of micro light-emitting diodes, wherein the color-conversion material is laterally disposed between the plurality of reflective banks.
