Abstract: Disclosed is an organic light emitting diode display including an organic light emitting display panel configured to display an image, and a lower passivation film attached to a bottom of the organic light emitting diode display panel. The lower passivation film includes a support film that is in contact with the organic light emitting diode display panel, and a stress adjustment layer formed beneath the support film and configured to reduce a bending stress to be induced in the organic light emitting display panel when the organic light emitting display panel and the lower passivation film are bent.

Abstract: Provided is a display device including: a bottom member; a display panel on the bottom member, the display panel configured to emit light; a top member on the display panel; a touch screen panel on the top member; and a groove region formed by removing at least a portion of at least one of the top member and the bottom member at a bent portion of the display device.

Abstract: A display device includes a display panel configured to display an image, and a protection film coupled to a lower portion of the display panel. The protection film includes a support film contacting the display panel and a stress control layer below the support film, and the stress control layer includes a plurality of nanobeads.

Abstract: A display apparatus may include a substrate, a pad unit on the substrate, a display panel on the substrate, an encapsulation layer covering the display panel, and a protective layer on the pad unit. The protective layer may have an elastic coefficient ranging from about 10 MPa to about 200 GPa.

Abstract: A measurement pigment composition including pigment particles may be coated on a surrounding area of a display panel to form a strain measuring part. A strain of the display device may be measured by using 3D images of the strain measuring part.

Abstract: In an aspect, a display device including a display panel, a first protecting film attached under the display panel, and a second protecting film attached on the second protecting film, in which at least any one of the first and second protecting films includes a retardation layer is provided.
