A display apparatus includes a first pixel, a second pixel, and a third pixel which emit light of different colors from one another, a first insulating layer on a first display element of the first pixel, and a second insulating layer on the first insulating layer. The first insulating layer defines a first opening portion corresponding to the first display element, the second insulating layer defines a first opening corresponding to the first opening portion, and the first opening portion has a first extension portion which extends in a first direction and at least partially exposes the second insulating layer.

An electronic device may have a hinge that allows the device to be flexed about a bend axis. A display may span the bend axis. To facilitate bending about the bend axis without damage, the display may include a display cover layer with a flexible portion. The flexible portion of the display cover layer may be interposed between first and second rigid portions of the display cover layer. The display cover layer may also include a layer with self-healing properties. The layer of self-healing material may be formed across the entire display cover layer or may be formed only in the flexible region of the display cover layer. The display cover layer may include a layer of elastomer in the flexible region of the display cover layer for increased flexibility. Self-healing may be initiated or expedited by externally applied heat, light, electric current, or other type of external stimulus.
