Abstract: A light emitting display device includes a substrate, an organic layer, a conductor, an anode, and a pixel definition layer. The organic layer overlaps the substrate and has a connection opening. The conductor is positioned between the substrate and the organic layer. The anode is positioned on the organic layer and is partially positioned inside the connection opening. The pixel definition layer exposes an exposed portion of the anode. The organic layer has a halftone exposure portion and a neighboring portion. The halftone exposure portion overlaps the exposed portion of the anode and overlaps the conductor. The neighboring portion neighbors the halftone exposure portion. A face of the halftone exposure portion and a face of the neighboring portion are spaced from the substrate by a first distance and a second distance, respectively. A difference between the first distance and the second distance is 30 nm or less.
