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.

Electroluminescence display device having a through-hole in display area

An electroluminescence display device including a substrate having a display area and a non-display area arranged near the 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, a second inorganic encapsulation layer and an organic encapsulation layer disposed between the first and second inorganic encapsulation layers, a through-hole arranged inside the display area to penetrate the substrate, an inner dam surrounding the through-hole, a trench arranged between the inner dam and the through-hole, and an etch-stopper arranged between the trench and the through-hole, wherein the first inorganic encapsulation layer and the second inorganic encapsulation layer are disposed on the display area and covering the inner dam and the trench.

An electroluminescence display device comprising a through-hole in a display area is discussed. The electroluminescence display device according to one embodiment of the present disclosure comprises a substrate having a display area and a non-display area arranged near the display area; a light emitting diode in the display area; an encapsulation layer on the light emitting diode; a through-hole arranged inside the display area to penetrate the substrate; an inner dam surrounding the through-hole; a trench arranged between the inner dam and the through-hole; and an etch-stopper arranged between the trench and the through-hole on the an insulating layer.

Disclosed is a display device which is capable of preventing an encapsulation film from being formed in a scribing line, and a method for manufacturing the same. The display device includes a substrate having a display area provided with pixels, a non-display area surrounding the display area, an encapsulation film including an inorganic film which covers the display area, and a buffer layer. The buffer layer is provided at a predetermined interval from the display area in the non-display area and is brought into contact with the edge of the inorganic film.
