Abstract
The present disclosure provides a light-emitting display device including a lower substrate, a transistor, a planarization layer, a sacrificial layer, an isolation layer, a lower electrode layer, an organic emission layer and an upper electrode layer. The isolation layer is positioned on the sacrificial layer, and exposes part of the planarization layer through an opening that extends through the isolation layer and the sacrificial layer. The planarization layer includes a first contact hole positioned in the opening, and the lower electrode layer is electrically connected to one electrode of the transistor through the first contact hole.
