Abstract: A display panel includes a pixel array substrate, a plurality of vertical light emitting devices and a flip-chip light emitting device. The pixel array substrate has a first pixel area and a second pixel area. The vertical light emitting devices are disposed in the first pixel area and the second pixel area and electrically connected to the pixel array substrate. The flip-chip light emitting device is disposed in the second pixel area and electrically connected to the pixel array substrate. A color of an emitted light beam of the flip-chip light emitting device and a color of an emitted light beam of one of the vertical light emitting devices located in the first pixel area are identical.
