Abstract: A light emitting display device and a method for fabricating the same. The light emitting display device includes a substrate, a first electrode arranged on the substrate, a first insulating film arranged on the substrate and including a first opening that exposes a portion of the first electrode, a second insulating film arranged on the first insulating film and including a second opening that exposes the first opening, a light emitting layer including a light emitting material arranged on the exposed portion of first electrode while also being in contact with the first insulating film and a second electrode arranged on the light emitting layer, wherein a difference in wetting between the first electrode and the first insulating film with respect to the light emitting material is lower than a difference in wetting between the first electrode and the second insulating film with respect to the light emitting material.
