Abstract

A display device includes a planarization layer disposed on a substrate, a first electrode disposed on the planarization layer and including silver (Ag), a contact preventing layer disposed on the first electrode, including a light absorbing material, and including a top surface and a side surface extending from an end of the top surface, and a pixel defining layer disposed on the contact preventing layer and including a bottom surface facing the top surface of the contact preventing layer, and a side surface extending from an end of the bottom surface. The first electrode includes a first region overlapping pixel defining layer. The contact preventing layer includes a second region overlapping the first region between the first electrode and the pixel defining layer. A first edge where the top and side surfaces of the contact preventing layer meet is located on the bottom surface of the pixel defining layer.
