Abstract

A display device includes a substrate including a pixel area and a transmission area, and a pixel circuit disposed in the pixel area. The pixel circuit includes a first thin-film transistor included in a first multi-layer film, and a second thin-film transistor included in a second multi-layer film on the first multi-layer film. The first thin-film transistor and the second thin-film transistor are electrically connected to each other. The display device also includes a display element disposed on the second multi-layer film and including a pixel electrode electrically connected to the second thin-film transistor via a contact hole defined in the second multi-layer film, an opposite electrode facing the pixel electrode, and an intermediate layer between the pixel electrode and the opposite electrode.
