Light-emitting display device including overhang structure formed by organic insulating film pattern

Abstract

Disclosed is a light-emitting display device having a configuration in which an organic insulating film pattern forming an overhang structure on an auxiliary wire is in direct contact with the auxiliary wire and contacts side surfaces of adjacent metal and insulating films via different tapers, so that structural robustness of an island-type structure can be obtained and connection to a cathode can be strengthened. The light-emitting display device includes an auxiliary wire on a substrate, a first insulating layer having a first hole on the auxiliary wire, a first metal layer having a second hole overlapping the first hole on the first insulating layer, a second insulating layer having a third hole overlapping the second hole on the first metal layer, a second metal layer having a fourth hole overlapping the third hole on the second insulating layer, and an organic insulating film pattern filling the first hole to the fourth hole and contacting the auxiliary wire.
