Micro light-emitting diode display device

A micro light-emitting diode display device, comprising a display area and a non-display area disposed at least partially around the display area, further comprising:

• a circuit substrate;
• an epitaxy structure, electrically connected to the circuit substrate, and comprising:
• a connection layer provided with a through hole in the non-display area;
• and
• a plurality of light-emitting mesas, disposed on the connection layer in the display area, wherein a thickness of the connection layer is less than a thickness of the light-emitting mesas, and the connection layer has a first surface exposed by the light-emitting mesas and a second surface opposite to the first surface;
• and
• a first conductive layer, disposed on the second surface of the connection layer and in the through hole to electrically connected to the circuit substrate, wherein a vertical projection of the first conductive layer onto the connection layer overlaps a vertical projection of the first surface onto the connection layer,
• wherein a plurality of sub-areas of the second surface corresponding to the light emitting mesas respectively are exposed.
