Display device and method of fabricating the same

A display device comprising:

• a base layer, the 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,
• wherein 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 disposed on the first surface and completely covering the first etch stopper layer, the second etch stopper layer being open in a region corresponding to the via holes, and wherein
• each of the via holes has an opening at the second surface of the base layer that is larger than an opening at the first surface of the base layer.
