Press detecting touch panel and display device

A press detecting touch panel comprising:

• a housing defining an opening;
• a piezoelectric film;
• and
• a holding member which holds the piezoelectric film within the opening, an entire periphery of the holding member being fixed to the housing such that the holding member covers the opening, a first cross sectional shape along a first direction of the holding member is different than a second cross sectional shape along a second direction of the holding member, the first direction and the second direction being orthogonal to each other, and a first curvature of a first main surface of the holding member is different from a second curvature of a second main surface of the holding member, the first main surface and the second main surface opposing each other, and each of the first main surface and the second main surface extending perpendicular to a stacking direction of the housing, the piezoelectric film and the holding member,
• wherein, when the holding member is bent by a pressing force applied to the first main surface thereof, a warp in a horizontal direction is less than a warp in a vertical direction of the holding member.
