A display apparatus capable of reducing a defect rate during manufacturing and utilizing thereof, the display apparatus includes a substrate comprising a display area and a peripheral area outside the display area; a display unit over an upper surface of the substrate to correspond to the display area; and a protective film including a protective film base and an adhesive layer, the protective film being attached to the lower surface of the substrate by the adhesive layer, wherein the protective film base includes a first protective film base corresponding at least to the display area, and a second protective film base having physical properties that are different from physical properties of the first protective film base and corresponding to at least a part of the peripheral area.

Display apparatus

A flexible display device including a display panel configured to display an image and including first and second bending areas configured to be bent along first and second folding axes, respectively, and a touch sensing unit disposed on the display panel. The touch sensing unit includes a base insulation layer, a first touch electrode part disposed on a first surface of the base insulation layer and overlapping the first bending area to detect an external input, and a second touch electrode part disposed on a second, opposing surface of the base insulation layer and overlapping the second bending area to detect an external input. A portion of the display panel is disposed between the first folding axis and the touch sensing unit, and a portion of the touch sensing unit is disposed between the second folding axis and the display panel, when the flexible display device is bent.

Flexible display device and method of manufacturing the same

A method of manufacturing a touch panel, the method including forming electrode patterns; forming insulating patterns on the electrode patterns; forming a sacrificial layer on the electrode patterns and insulating patterns such that the sacrificial layer includes openings exposing portions of the insulating patterns; forming a conductive layer on the sacrificial layer and in each of the openings; and removing the sacrificial layer to form bridge patterns corresponding to the openings, wherein the sacrificial layer includes a first layer including first openings therein that expose portions of the insulating patterns; and a second layer including second openings therein that expose portions of the insulating patterns, the second layer having a thickness that is larger than a thickness of the first layer.

Method of manufacturing touch panel

A flexible display device includes a flexible display panel, an outer member disposed on a surface of the flexible display panel and including an electrode layer, and a stress control member disposed between the flexible display panel and the outer member, where the stress control member allows neutral planes to be defined in the flexible display panel and the outer member, respectively, when the flexible display device is bent, the outer member includes a touch panel including the electrode layer, a flexible member disposed on the touch panel, and an adhesive layer disposed between the touch panel and the flexible member and which couples the touch panel to the flexible member, and a neutral plane of the outer member is defined in the touch panel.

Flexible display device
