Holding structure for a touch panel

A holding structure for a touch panel, comprising:

• a display panel for forming a display screen;
• a touch panel disposed outside the display panel, for allowing an input operation;
• a supporting frame for holding the display panel at an entire peripheral edge thereof and supporting the touch panel in parallel with the display panel;
• a piezoelectric device disposed at a side edge of the touch panel, for applying vibration to the touch panel in accordance with the operation of the touch panel;
• a casing for holding the display panel and the touch panel via the supporting frame, the casing having an opening through which the touch panel is exposed;
• and
• a flexible resin sheet integrally provided to the touch panel on a front surface side of the touch panel, wherein
• the flexible resin sheet is formed to have a size entirely larger than a glass substrate provided to the touch panel on a rear surface side of the touch panel, the flexible resin sheet being held at a peripheral edge thereof by a rear surface of a peripheral edge of the opening of the casing and a supporting member fixed to the casing, and
• the peripheral edge of the flexible resin sheet is sandwiched, at an entire periphery, between a holding projection that projects from the rear surface of the peripheral edge of the opening of the casing and a projection edge that projects from a front surface of the supporting member, and is held by the holding projection and the projection edge.
