Abstract

A display device is provided. The display device includes a substrate having a non-display portion, a display area surrounding at least a portion of the non-display portion, and a non-display area disposed adjacent to the display area; a display unit disposed on the first insulating layer in the display area, and including a plurality of pixels surrounding the non-display portion, in which each pixel includes a light emitting element including a pixel electrode and a counter electrode facing each other, and an emission layer disposed between the pixel electrode and the counter electrode; and a plurality of dummy pixels disposed adjacent to the display unit in a plan view and including a metal pattern including the same material as the pixel electrodes.
