Abstract
The present disclosure provides a light-emitting display device including a first substrate, sub-pixels and contact holes. Each sub-pixel is positioned on the first substrate and has an emission area from which light is emitted. The contact is positioned in a hole in the emission area and serves to electrically connect a transistor of the sub-pixel to a light-emitting diode emitting light and an emission layer on the contact is to emit light in the same color as the light emitted from the emission area.
