Abstract
A display device includes a base layer including a first surface and a second surface, pixels and first lines that are disposed on the first surface, second lines disposed on the second surface and corresponding to the first lines, a multi-layered etch stopper layer disposed on the first surface and disposed between the base layer and the first lines, and via holes penetrating the base layer and the multi-layered etch stopper layer, the via holes connecting the first lines to the second lines. The multi-layered etch stopper layer includes a first etch stopper layer disposed on the first surface and surrounding each of the via holes, the first etch stopper layer including an inorganic layer, and a second etch stopper layer entirely disposed on the first surface including the first etch stopper layer, the second etch stopper layer being open in a region corresponding to the via holes.
