Abstract: A display device may include: a substrate including a plurality of sub-pixels, including a first sub-pixel; an insulating layer disposed over the substrate and having a first open area in the first sub-pixel, the insulating layer having a side portion facing the first open area in the first sub-pixel; an anode electrode including a first portion disposed in the first open area and a second portion disposed on the side portion of the insulating layer; an organic layer on the anode electrode; and a cathode electrode on the organic layer. The first open area of the insulating layer may have an uneven outer edge in a plan view.
