Abstract

Provided is a display device comprising a substrate, a first data line and a second data line disposed on the substrate and extended in a first direction, an anode electrode disposed on the first data line and the second data line, a pixel-defining film disposed over the anode electrode and defining an emission area, an organic light-emitting layer disposed on the anode electrode, and a cathode electrode disposed on the organic light-emitting layer, wherein each of the first data line and the second data line has a curved shape when viewed from a top where the first anode electrode and the second anode electrode overlap the anode electrode.
