Abstract
Disclosed is a display device capable of exhibiting improved reliability and stability. The display device includes an uneven part, which is disposed on a bending area of an upper substrate, on which a touch sensor is disposed. Therefore, each of routing lines disposed on the uneven part has an uneven surface that is formed along the uneven part within the bending area. Accordingly, cracking or disconnection of the routing lines is prevented during bending of the display device, and consequently reliability and stability are improved.
Claims20
A display device comprising:
- a touch sensor disposed on an upper substrate;
- a light-emitting unit disposed on a lower substrate facing the upper substrate;
