Abstract

The present disclosure relates to a display device including: a display panel; a support member disposed on a surface of the display panel; and an adhesive layer disposed between the support and the display panel, in which the support includes: a plurality of metal layers spaced apart from each other; and a buffer layer surrounding the plurality of metal layers, the adhesive layer including: a first region overlapping the plurality of metal layers in a vertical direction to the display panel; and a second region that does not overlap the plurality of metal layers in the vertical direction to the display panel, and a modulus of the second region of the adhesive layer is greater than a modulus of the first region of the adhesive layer.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2020-0146153 filed with the Korean Intellectual Property Office on November 4, 2020, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to a display device, and to a display device preventing deformation of a rollable display device. Background technique [0004] Recently, with the development of display-related technologies, display devices having a structure that can be changed during use, such as being folded, rolled into a roll, and stretched like a rubber band, have been researched and developed. Since these display devices can be modified in various forms and ways, they can satisfy both the demand for large-sized displays and the demand for small-sized, portable displays. [0005] When the display device is folded or rolled, stress is applied to con...
