Micro light-emitting diode display panel

A micro light-emitting diode display panel, comprising:

• a first substrate;
• a second substrate disposed opposite to the first substrate;
• a plurality of micro light-emitting diodes disposed on the first substrate and respectively located in a plurality of sub-pixel areas, and the micro light-emitting diodes are adapted to emit a light beam;
• a wavelength conversion layer overlapped with at least a portion of the micro light-emitting diodes and located between the at least a portion of the micro light-emitting diodes and the second substrate, wherein the light beam is used to excite the wavelength conversion layer to emit a converted light beam;
• a light-shielding pattern layer disposed on the second substrate and having a plurality of first openings defining the sub-pixel areas;
• a light filter layer disposed between the wavelength conversion layer and the second substrate and overlapped with the micro light-emitting diodes;
• and
• an air gap disposed between any two adjacent ones of any one of the micro light-emitting diodes, the second substrate, the wavelength conversion layer, and the light filter layer.
