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.
