Abstract: A light emitting display device includes: a substrate; a first, a second, and a third conductive pattern on the substrate and extending in a first direction; an organic film covering the first, the second, and the third conductive pattern; an anode on the organic film; and a pixel defining layer having an opening overlapping the anode. The opening of the pixel defining layer overlaps the first, the second, and the third conductive pattern in a plan view. The first, the second, and the third conductive pattern are sequentially positioned in a second direction perpendicular to the first direction. In a portion overlapping the opening of the pixel defining layer in a plan view, a gap between the first conductive pattern and the second conductive pattern in the second direction and a gap between the second conductive pattern and the third conductive pattern in the second direction are the same.

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.
