Abstract
An electronic device includes a touch panel; a light shielding film formed on a first principal surface of a touch panel corresponding to a non-operation area; and a vibrator provided on a second principal surface of the touch panel corresponding to the non-operation area. When a critical angle at which light is totally reflected by the second principal surface of the touch panel is θ and sum of a thickness Tof the touch panel and a thickness Tof the vibrator is T, the vibrator is positioned, in sectional view, within a range of T×tan θ from an end on the operation area side of the light shielding film on the second principal surface of the touch panel corresponding to the non-operation area, and a reflection-reducing film having a reflectance lower than a reflectance of a surface of the vibrator is provided on the surface of the vibrator positioned within the range of T×tan θ from the end on the operation area side of the light shielding film.
