Abstract
A display panel is provided. The display panel includes a display region and a non-display region. The display region includes a first substrate, containing an N-type semiconductor layer including a plurality of protrusions and a plurality of light-emitting diodes. Each light-emitting diode includes an island-shaped structure. The island-shaped structure includes a protrusion, a light-emitting layer, and a P-type semiconductor layer. The display region also includes an N electrode and a plurality of P electrodes. The N electrode has a mesh structure, and the island-shaped structure is disposed in a mesh opening of the mesh structure. The N electrode is electrically connected to the N-type semiconductor layer. The plurality of P electrodes are disposed, in a one-to-one correspondence with the plurality of light-emitting diodes, on a side opposite to the N-type semiconductor layer. Each P electrode is electrically connected to the P-type semiconductor layer.
