Original Abstract Submitted
A display device includes a substrate including a display area including pixels, and a dummy area including dummy pixels, a pixel circuit layer including a transistor, and a via layer above the transistor, bank patterns above the via layer, light-emitting elements between the bank patterns in plan view, a first bank above a portion of the bank patterns, a second bank above the first bank, and including an edge bank defining an outermost boundary of the dummy area, covering an inner side of an edge bank pattern of the bank patterns overlapping the edge bank, and covering an inner side of a portion of the first bank that overlaps the edge bank, the first bank and the second bank partitioning emission areas and dummy opening areas, and a light conversion layer in the emission areas and in the dummy opening areas, which correspond to openings of the second bank.
