    Abstract: The present invention provides a display panel and a manufacturing method thereof. The display panel comprises a micro light emitting diode and a thin film transistor electrically coupled to the micro light emitting diode. The micro light emitting diode comprises a P type semiconductor and a N type semiconductor. The P type semiconductor is close to the thin film transistor and the N type semiconductor is configured at one side of the P type semiconductor away from the thin film transistor. One surface of the N type semiconductor away from the P type semiconductor is roughened by a plasma surface treatment process. Since a thickness of the N type semiconductor is larger than a thickness of the P type semiconductor, the crystal quality of material of the N type semiconductor will not be affected as the N type semiconductor is roughened to increase the light efficiency.
