Abstract: A display device includes an array substrate including a pixel array disposed in a display area, and a fan-out wiring disposed in a peripheral area adjacent to the display area. The fan-out wiring is disposed in a sealing area surrounding the display area. The display device includes a cover substrate combined with the array substrate by a sealing member disposed in the sealing area. The fan-out wiring includes a first fan-out line, a second fan-out line, and a third fan-out line, which are disposed in different layers in a first peripheral area between the display area and the sealing area. The first fan-out line and the second fan-out line are disposed in a same layer in the sealing area, and the first fan-out line and the third fan-out line are disposed in different layers in the sealing area.
