Abstract
Disclosed is a light emitting diode display device in which a process time taken in a process of connecting a light emitting device to a pixel circuit is shortened. The light emitting diode display device includes a pixel including a driving thin film transistor (TFT) on a substrate, a first planarization layer covering the pixel, a concave portion in the first planarization layer, a light emitting device in the concave portion and including a first electrode and a second electrode, a second planarization layer covering the first planarization layer and the light emitting device, a pixel electrode electrically connected to the driving TFT and the first electrode of the light emitting device, and a common electrode electrically connected to the second electrode of the light emitting device. The pixel electrode and the common electrode are on the second planarization layer.
