摘要：
A display device includes: a display area and a non-display area; anode electrodes in the display area; an inorganic insulating layer on the anode electrodes; a bank structure on the inorganic insulating layer, and including openings overlapping with the anode electrodes; light emitting layers on the anode electrodes and in the openings; cathode electrodes on the light emitting layers and in the openings; a first power line in the non-display area; and a power connection electrode including through portions partially overlapping with the first power line, and between the first power line and the display area. The bank structure includes: hole patterns on the power connection electrode in the non-display area, and overlapping with the through portions; a first bank layer; and a second bank layer on the first bank layer. The second bank layer includes a tip protruding from a sidewall of the first bank layer.
