Micro light-emitting diode structure and display panel device

A display panel device comprising:

• a driving carrier;
• and
• a plurality of micro light-emitting diode structures electrically connected to and driven by the driving carrier, and each micro light-emitting diode structure comprising:
• a first-type semiconductor layer having a first width on a cross-section of the micro light-emitting diode structure;
• a second-type semiconductor layer disposed on a side of the first-type semiconductor layer and having a second width on the cross-section of the micro light-emitting diode structure;
• a light-emitting layer disposed between the first-type semiconductor layer and the second-type semiconductor layer and having
• an extended part laterally protruding from at least two sides of the light-emitting layer relative to the first-type semiconductor layer and the second-type semiconductor layer, and the extended part exposes a part of an upper surface and a part of an underside surface of the light-emitting layer;
• and
• a third width greater than the first width and the second width on the cross-section of the micro light-emitting diode structure;
• and
• a base layer disposed on a side of the second-type semiconductor layer away from the first-type semiconductor layer and having a fourth width greater than the second width.
