Electroluminescence display device having a through-hole in display area

An electroluminescence display device comprising:

• a substrate having a display area and a non-display area arranged near the display area;
• a light emitting diode disposed in the display area;
• an encapsulation layer disposed 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;
• an upper passivation film disposed on the second inorganic encapsulation layer;
• a through-hole arranged inside the display area to penetrate the substrate;
• an inner dam surrounding the through-hole;
• a trench disposed between the inner dam and the through-hole;
• and
• a buffer layer on which a thin film transistor is arranged, the thin film transistor electrically connected to the light emitting diode,
• wherein the buffer layer is disposed on the display area except at the through-hole and passes below the inner dam and the trench,
• wherein the first inorganic encapsulation layer and the second inorganic encapsulation layer cover the inner dam and the trench in the display area,
• wherein the trench includes a recessed portion recessed to reach an upper surface of the buffer layer between the through-hole and the inner dam, and
• wherein the light emitting diode includes a light emitting layer that is disconnected at the trench.
