Abstract

A display device to an embodiment of the present disclosure comprises a display panel including an active area having a bending area, a first touch sensitive element which overlaps the active area ofthe display panel and includes a first electroactive layer, a bending member which is disposed below the display panel and overlaps at least the bending area, and a second touch sensitive element including a second electroactive layer which covers the bending member. Therefore, in the bending area where the stress due to the bending is concentrated, the lifespan and the driving stability of the first touch sensitive element and the second touch sensitive element may be improved.

Description

technical field [0001] The present disclosure relates to a touch-sensitive element and a display device including the touch-sensitive element, and more particularly, to a touch-sensitive element which increases resistance to deformation in a bending region and improves lifespan when the touch-sensitive element is bent, and a display device including the touch-sensitive element. A display device with a touch-sensitive element. Background technique [0002] A touch panel is a device that senses a user's touch input (eg, screen touch on a display device) or gesture, and is widely used in portable display devices such as smartphones and tablet PCs, and display devices such as public facilities and smart TVs in large-size display devices. Operation modes of the touch panel include a resistive type, a capacitive type, an optical type, an electromagnetic (EM) type, and the like. [0003] Recently, however, haptic devices are being researched as touch sensitive elements that not o...
