Abstract: A light-emitting diode (LED) chip and a display device having the same are provided. A green LED is regrown on a blue LED to produce blue and green light, and a red phosphor is disposed on the blue or green LED to produce red light. Red light, green light, and blue light are to be produced using a single LED chip. The single LED chip forms three subpixels therein so as to facilitate a transfer process of the LED chip to a display panel. The LED chip is configured based on the blue, green, and blue LEDs so as to facilitate the fabrication and driving of the LED chip.
