Abstract
Discussed is an electroluminescence display device including a substrate having a display area and a non-display area, a light emitting diode in the display area, an encapsulation layer on the light emitting diode, the encapsulation layer including a first inorganic encapsulation layer, and a second inorganic encapsulation layer, an upper passivation film on the second inorganic encapsulation layer, a through-hole inside the display area to penetrate the substrate, an inner dam surrounding the through-hole, a trench between the inner dam and the through-hole, a buffer layer, and a thin film transistor electrically connected to the light emitting diode. The buffer layer is on the display area except at the through-hole and passes below the dam and the trench. The first and second inorganic encapsulation layers cover the inner dam and the trench. The trench includes a recessed portion, and the light emitting diode includes a light emitting layer.
