ABSTRACT:
An electronic device includes a housing and a touch sensor mounted in the housing. The touch sensor further includes a translucent panel provided in a part of the housing, a printed circuit board which senses a touch on the translucent panel by a user, a light source mounted to the printed circuit board, which irradiates light towards the translucent panel, and a diffusion sheet provided between the translucent panel and the light source, which diffuses the light irradiated from the light source. The diffusion sheet further includes a first region formed transparent to directly transmit the light, and a second region frosted to diffuse the light towards an outer peripheral portion of the translucent panel. The second region is provided at a position corresponding to the light source, and the first region is provided to surround the second region.
