Micro light-emitting diode display device and manufacturing method thereof

A method of manufacturing a micro light emitting diode display device, comprising steps of:

• providing a substrate;
• forming micro light-emitting diodes for emitting blue light on an upper surface of the substrate;
• forming a protective layer on the upper surface of the substrate to simultaneously cover the micro light-emitting diodes and the substrate;
• forming a black matrix layer having a lattice pattern on an upper surface of the protection layer;
• forming a yellow phosphor layer that is filled in the black matrix layer pattern and on the upper surface of the protective layer, wherein the yellow phosphor layer is formed with light-transmitting holes at intervals opened to the surface and has a thickness smaller than the thickness of the black matrix layer;
• and
• forming a color filter layer in the black matrix layer pattern and in the light-transmitting holes, wherein the color filter layer comprises a red filter area, a green filter area and a light-transmitting area, and the light-transmitting area is right opposite to the corresponding light transmitting hole.
