Abstract:
An electronic device includes a touch panel having a first principal surface and a second principal surface positioned opposite to the first principal surface; a light shielding film formed on the first principal surface of the touch panel corresponding to a non-operation area; and a vibrator provided on the second principal surface of the touch panel corresponding to the non-operation area. When a critical angle where light is totally reflected by the second principal surface of the touch panel is represented by θ and sum of a thickness T1 of the touch panel and a thickness T2 of the vibrator is represented by T, the vibrator is provided, on the second principal surface of the touch panel corresponding to the non-operation area, at a position apart by T×tan θ or more from an end of the light shielding film which end is positioned on the operation area side, in sectional view.
