Electronic device

An electronic device comprising a housing and a touch sensor mounted in a part of the housing, wherein the touch sensor further comprising:

• a translucent panel including a part indicating at least one of character, pattern and symbol;
• a printed circuit board which senses a touch on the translucent panel by a user;
• a light emitting diode mounted in the printed circuit board at a position directly opposing the part indicating said at least one of character, pattern and symbol, which irradiates light towards the translucent panel;
• and
• a diffusion sheet provided between the translucent panel and the light emitting diode, which diffuses the light irradiated from the light emitting diode, and
• the diffusion sheet further comprising:
• 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 part indicating said at least one of character, pattern and symbol of the translucent panel, wherein
• the first region being provided to surround the second region, and
• the second region is a region provided at a section of the diffusion sheet, which directly faces the light emitting diode.
