A guide film includes a main area, a first subsidiary area, and a second subsidiary area being apart from the first subsidiary area. The main area includes a central area having a rectangular shape in a plan view, a first side area arranged between the central area and the first subsidiary area, a second side area arranged between the central area and the second subsidiary area, and a first corner area connecting the first side area to the second side area.

Guide film and method of manufacturing display apparatus

Provided is a display apparatus including a substrate having an island and a plurality of connection parts extending in different directions from an end of the island and connected to different islands; a display region disposed on the island and including a display element connected to a common electrode; a common voltage power line disposed on the island and on at least one first connection part of the plurality of connection parts extending from the island; and at least one contact portion disposed on the at least one first connection part, wherein the at least contact portion is connected to the common electrode and the common voltage line.

Display apparatus

A display device includes a display panel and an input sensing layer. The display panel includes a base layer including a first island part, a second island part, and a connection part. Sensing patterns of the input sensing layer include a first sensing line pattern disposed on both the first island part and the second island part, and a second sensing line pattern disposed on the connection part. The connection part is an area to which stress is applied as the display device is modified in shape. The second sensing line pattern is disposed on an area of the connection part to which relatively less stress is applied.

Display device

A display device includes: a substrate including an island portion and at least one connection portion extending from the island portion; a display unit on the island portion, the display unit including at least one display element; and an encapsulation layer covering the at least one display element and including an inorganic encapsulation layer and an organic encapsulation layer, wherein the display unit includes: at least one organic insulating layer; and an inorganic insulating layer on the at least one organic insulating layer, the inorganic insulating layer having a tip protruding beyond a side surface of the at least one organic insulating layer, in a direction parallel to an upper surface of the substrate, and the inorganic encapsulation layer is alongside the tip of the inorganic insulating layer.

A stretchable display device includes a display area having stretchable display units each including first islands on which pixels are disposed and first cut-out grooves between the first islands. A peripheral area is adjacent to the display area, the peripheral area includes stretchable peripheral units each including first lines on which driving circuits are disposed and first opening portions between the first lines. A buffer area is disposed between the display area and the peripheral area. The buffer area includes stretchable buffer units each including second islands, second cut-out grooves between the second islands, second lines connected to the second islands, and second opening portions between the second lines. Shapes of the second cut-out grooves may be different from shapes of the first cut-out grooves, and shapes of the second opening portions may be different from shapes of the first opening portions.
