摘要： A display device can include a display panel including a non-display area and a display area. The display area can include a first area, a third area surrounded by the first area, and a second area disposed between the first area and the third area. Here, at least one of the first, second, and third area can include a plurality of light emitting areas and a plurality of transmission areas. The display device can further include an optical electronic device located under, or in a lower portion of, the display panel and overlapping at least a portion of the first area included in the display area. The display panel can include a light shield layer disposed under transistors in the plurality of light emitting areas and not disposed in the plurality of transmission areas.

摘要： Discussed herein is a transparent light emitting diode (LED) display device. A capacitor of a pixel-driving circuit is integrated with an LED, and thus that the area of the pixel-driving circuit is reduced, and the transmission area is increased. In this manner, it is possible to achieve high transmittance without compromising the display quality.

摘要： A light emission element includes a first semiconductor layer, a light emission layer, and a second semiconductor layer. The first semiconductor layer in the light emission portion is provided with a concave portion having a concave shape. The light emission layer and the second semiconductor layer disposed on the first semiconductor layer are also disposed along the concave shape of the concave portion. The light emitting layer disposed along the shape of the concave portion emits light by electrons and holes injected from the first semiconductor layer and the second semiconductor layer. Further, the light path of the light emitted according to the concave shape is adjusted. Therefore, a light emission element having improved light efficiency and a display device using the same can be provided.
