Display device comprising backlight device, detection electrodes, and elastic member

A display device comprising:

• a liquid crystal panel comprising a first substrate, a second substrate opposing the first substrate, a liquid crystal layer between the first substrate and the second substrate, and a first detection electrode on the first substrate or the second substrate;
• a backlight device opposed to the first substrate via an air layer, and comprising a light guide, an optical sheet on the light guide and a light source which input light into the light guide;
• a second detection electrode opposing the first detection electrode via the backlight device;
• and
• an elastic member between the backlight device and the second detection electrode, comprising a first region opposing a central portion of the backlight device and a second region located to surround the first region, the first region and the second region being different in hardness in a thickness direction of the elastic member,
• wherein the elastic member comprises a plurality of holes formed in the first region and the second region, and a density of the holes in the first region is higher than that of the holes in the second region.
