Abstract: A stretchable display device includes a substrate having a plurality of islands spaced apart from each other, and a plurality of bridges connecting each of the plurality of islands. A plurality of display units is disposed above the plurality of islands, respectively. A plurality of metal wirings are electrically connected to each of the plurality of display units. The plurality of metal wirings are disposed above the plurality of bridges. Each of the plurality of bridges includes a first region curved convexly in a first direction on a plane, and a second region curved concavely in the first direction. The second region is connected to the first region. Each of the plurality of metal wirings has a first width, and each of the plurality of bridges have a second width that is greater than the first width.

Abstract: A display apparatus includes: a substrate; a first electrode; an insulating film including an opening that extends to at least the central portion of the first electrode; a light-emitting diode disposed on the first electrode and including a first pad electrically connected to the first electrode; a reflective film disposed on the insulating film so as to cover at least a portion of an inner surface of the opening; and a light path guide layer disposed on the insulating film so as to cover at least a portion of the reflective film and including a plurality of holes or a plurality of grooves on the top surface. In one embodiment, the display apparatus improves the light extraction efficiency of the light-emitting diode.
