Abstract
Provided are a display device and a method of manufacturing the same. A display device includes: a lower substrate, a first over-coat layer on the lower substrate, the first over-coat layer including a first contact hole, a thin film transistor between the lower substrate and the first over-coat layer, the thin film transistor including a drain electrode including an end portion overlapping the first contact hole, the end portion of the drain electrode including an under-cut region, a lower passivation layer between the thin film transistor and the first over-coat layer, the lower passivation layer partially exposing a side surface of the end portion of the drain electrode, and a light-emitting structure on the first over-coat layer, the light-emitting structure being electrically connected to the thin film transistor through the first contact hole.
