Abstract
A display pixel suitable for being arranged on a carrier is provided. The display pixel includes a plurality of light-emitting diode chips. The light-emitting diode chips are disposed on and electrically connected to the carrier. Each of the light-emitting diode chips respectively serves as a sub-pixel and includes a semiconductor device layer, and the semiconductor device layer includes a display light-emitting mesa and at least one redundant light-emitting mesa. During a period of driving each of the light-emitting diode chips, one of the display light-emitting mesa and the at least one redundant light-emitting mesa in each of the light-emitting diode chips is capable of emitting light. A display panel including a plurality of the display pixels mentioned above is also provided.
