    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.
