Abstract
An electroluminescence display device having a through-hole in a display area is discussed. The electroluminescence display device can include a substrate, a through-hole, an inner dam, and a hole-trench. The substrate includes a display area where a plurality of pixels for displaying images are arranged, and a non-display area surrounding the display area. The through-hole is arranged inside the display area. The inner dam surrounds the through-hole. The hole-trench surrounds the inner dam, and is formed as the substrate is partially recessed as much as a certain thickness.
