Abstract:
An electroluminescent display device is provided. The device includes a substrate on which a display area displaying an image and a non-display area surrounding the display area are defined. The device includes a thin film transistor and a light-emitting diode disposed in the display area on the substrate and electrically connected to each other. The device further includes an encapsulation part covering the thin film transistor and the light-emitting diode, a touch sensor part on the encapsulation part, and first and second crack stoppers disposed in the non-display area on the substrate. The second crack stopper is disposed between the first crack stopper and the display area. The first crack stopper includes a first pattern that is formed through a same process as an electrode layer of the touch sensor part.
