Abstract
A high-resolution display device is provided. The high-resolution display device includes a light-emitting layer including a first semiconductor layer, an active layer, and a second semiconductor layer, a plurality of transparent electrodes respectively formed on the second semiconductor layer in sub-pixel regions, a first electrode connected to the first semiconductor layer, a plurality of second electrodes connected to the plurality of transparent electrodes, a color-converting layer arranged over the light-emitting layer and configured to emit light of a predetermined color based on light generated by the light-emitting layer, which are sequentially stacked on a substrate including a plurality of sub-pixel regions. One or more ion injection regions corresponding to current injection regions corresponding to the plurality of the sub-pixel regions is formed in the second semiconductor layer.
