Abstract
A display device includes: a substrate having a display area and a non-display area disposed around the display area; an organic light emitting diode disposed on the substrate in the display area; and a spacer disposed on the substrate in the non-display area, the substrate includes a first insulating film and a second insulating film disposed on the first insulating film, the substrate includes a groove disposed in an edge area farther from the organic light emitting diode than the spacer in the non-display area, and the groove is formed in at least one of the first insulating film and the second insulating film.
Claims13
A display device comprising:
- a substrate comprising a display area and a non-display area disposed around the display area;
- an organic light emitting diode disposed on the substrate in the display area;
- and
- a spacer disposed on the substrate in the non-display area,
- wherein the substrate comprises a first insulating film and a second insulating film disposed on the first insulating film,
