LIGHT-EMITTING DEVICE AND DISPLAY DEVICE USING THE SAME

Abstract:

A light-emitting device and a display device using the same are disclosed. The light-emitting device improves the reliability of a process of disposing light-emitting devices. The light-emitting device is configured to ensure electrical connections even if the light-emitting device is inverted while being disposed on a substrate. The light-emitting device includes an n-type semiconductor layer and a p-type semiconductor layer. N-type electrodes and p-type electrodes are disposed on both sides of top and bottom surfaces of the light-emitting device. Contact holes are provided to electrically connect one of the n-type electrodes to the n-type semiconductor layer and one of the p-type electrodes to the p-type semiconductor layer. When the light-emitting device is inverted while being disposed on a substrate, the light-emitting device operates ordinarily, thereby reducing the defect rate of a display device.
