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.
