Abstract:
An information display device (1A) comprises a touch panel (TP), an information display panel (LCD) located under the touch panel (TP) and four strip-like piezoelectric elements (E), which are caused to be vibrated and displaced by a pressing force generated when the touch panel (TP) is pressed, being disposed at the outer peripheral portion of the touch panel (TP), wherein both end portions of each strip-like piezoelectric element (E) are supported by surface-like holders (112A, 112B) with twist resilient deformation structures and a rotary shaft (113) so that each strip-like piezoelectric element (E) may not be disturbed from being vibrated and displaced. In this touch panel type information device, both end portions of a plurality of strip-like piezoelectric elements are supported by the supporting member having the holders with the twist resilient deformation structure which do not disturb both end portions of the strip-like piezoelectric elements from being vibrated and displaced.
