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.

Abstract: A rollable OLED display device according to an embodiment of the present disclosure is provided. The rollable OLED display device includes a rollable OLED display panel and a rolling unit. The rollable OLED display panel includes a display area and a non-display area that extends from the display area and includes a rolling unit attachment area. The rolling unit is in operative contact with the rolling unit attachment area of the rollable OLED display panel. It is configured to rotate such that the rollable OLED display panel is in a rolled state and an unrolled state. The rolling unit is formed in a cylindrical shape, and the rolling unit attachment area is defined by an arc of the cylindrical shape having an angle of 355° or less.
