Abstract
A display device includes a substrate which includes a display area and a non-display area adjacent to the display area, a first planarization layer which is at least partially disposed in the display area, a second planarization layer which is disposed in the non-display area and is spaced apart from the first planarization layer, a contact unit disposed between the first planarization layer and the second planarization layer in the non-display area, and a cathode which extends from the display area to the non-display area to be electrically connected to the contact unit. Accordingly, the first planarization layer and the second planarization layer are spaced apart from each other so that a path through which moisture permeates into the display area through the second planarization layer may be blocked.
