Claim 0:
1. A micro light-emitting diode display panel, comprising:
a substrate, comprising a plurality of pixel regions arranged in an array;
a first micro light-emitting diode, disposed on one of the pixel regions of the substrate;
a first light-shielding wall, disposed on the substrate and located completely around the first micro light-emitting diode;
a second micro light-emitting diode, disposed on the one of the pixel regions of the substrate and located beside the first micro light-emitting diode;
a second light-shielding wall, disposed on the substrate and located completely around the second micro light-emitting diode, wherein a light wavelength of the first micro light-emitting diode is different from a light wavelength of the second micro light-emitting diode, and a height of the first light-shielding wall is smaller than a height of the second light-shielding wall;
a first reflector, located within the first light-shielding wall and arranged around the first micro light-emitting diode, and having a first inclined surface inclined toward the first micro light-emitting diode;
a first transparent insulating layer, filled between the first micro light-emitting diode and the first inclined surface;
a second reflector, located within the second light-shielding wall and arranged around the second micro light-emitting diode, and having a second inclined surface inclined toward the second micro light-emitting diode; and
a second transparent insulating layer, filled between the second micro light-emitting diode and the second inclined surface, wherein a refractive index of the first transparent insulating layer is smaller than a refractive index of the first micro light-emitting diode, and a refractive index of the second transparent insulating layer is smaller than a refractive index of the second micro light-emitting diode,
wherein the first transparent insulating layer directly contacts a side wall of the first micro light-emitting diode, the first reflector directly contacts the first transparent insulating layer, the second transparent insulating layer directly contacts a side wall of the second micro light-emitting diode, and the second reflector directly contacts the second transparent insulating layer,
the first reflector is different and separated from the first light-shielding wall, the second reflector is different and separated from the second light-shielding wall.
