Abstract: According to an aspect of the present disclosure, a display device includes a substrate having an active area and a non-active area where sub pixels are disposed in the active area, a first assembly line and a second assembly line disposed in the sub pixels and being separated from each other to form a separated space, a light emitting diode disposed in the sub pixels and disposed on the first assembly line and the second assembly line, and a capacitor disposed below the first assembly line and the second assembly line. The capacitor is disposed so as to overlap the separated space formed between the first assembly line and the second assembly line. By this configuration, the light extraction of the display device can be improved.

Abstract: According to an aspect of the present disclosure, a display device includes a substrate in which a plurality of sub pixels is defined; a light emitting diode disposed on the substrate in each of the plurality of sub pixels; and a planarization layer which covers the light emitting diode and includes a first contact hole overlapping the light emitting diode. The first contact hole is formed to have a width which is narrowed from an upper portion of the first contact hole toward a lower portion of the first contact hole. Accordingly, the first contact hole is formed to have a step shape so that the exposure of the side surface part of the light emitting diode through the first contact hole and the disconnection of the pixel electrode may be minimized.
