Abstract

A display apparatus including a light-emitting device is disclosed. The light-emitting device is on a display area of a device substrate. An overcoat layer is disposed between the device substrate and the light-emitting device. The overcoat layer extends on a bezel area of the device substrate. A heating signal wiring is between the bezel area of the device substrate and the overcoat layer. A heating pattern electrically connected to the heating signal wiring is on the over-coat layer of the bezel area. A surface of the heating pattern opposite to the device substrate may be in contact with an adhesive layer covering the light-emitting device. Thus, in the display apparatus, the damage of the light-emitting device due to external moisture may be prevented or at least reduced.
