Document Type and Number:
WIPO Patent Application WO/2024/080669
Kind Code:
A1
Abstract:
Provided are a display device and a manufacturing method therefor. The display device comprises: a data conductive layer disposed on a substrate; a passivation layer disposed on the data conductive layer and including a first opening; a protective layer disposed on the passivation layer; a via layer disposed on the protective layer and including a second opening that overlaps the first opening; a connection electrode that is disposed inside the first opening and the second opening and spaced apart from a pixel electrode disposed on the via layer; a pixel defining film that is disposed on the pixel electrode and the connection electrode and includes an opening hole overlapping the second opening; a light-emitting layer disposed on the pixel definition film; and a common electrode disposed on the light-emitting layer and electrically connected to a first power line. The data conductive layer includes: a data base layer; a data main metal layer; and a data capping layer. The first power line includes a line connection structure formed such that the data main metal layer is recessed further than the side surface of the data capping layer, and the common electrode is electrically connected to the data main metal layer in the line connection structure.
