Abstract: A display device includes: a display area and a non-display area positioned around the display area and including a pad portion and a contact portion that is disposed between the display area and the pad portion; a first circuit portion including an embedded circuit disposed in the display area, a first connection electrode disposed in the pad portion, and a second connection electrode disposed in the contact portion; and a second circuit portion disposed on a layer different from the first circuit portion and including a pixel disposed in the display area, a pad disposed in the pad portion, and a data line extending across the contact portion and the display area and electrically connected to the pixel. The pad is electrically connected to the embedded circuit through the first connection electrode. The data line is electrically connected to the embedded circuit via the second connection electrode.
