Abstract

To provide a display device including a touch sensor, in which input feeling can be obtained and deterioration of image quality is suppressed. The display device includes a touch sensor portion, a display panel, an elastic member, and a support. The touch sensor portion is provided over the display panel. The support is provided below the display panel. The elastic member is provided between the display panel and the support. The elastic member is provided in part of the periphery of a pixel region included in the display panel or in the entire periphery.

First claim

1 . (canceled)

2 . A semiconductor device comprising:
