Abstract

PURPOSE:To electrify a transparent conductive film so as to input a signal through pushing any point of a touch face, and to prevent input error by insulating between each transparent conductive film through liquid or gas instead of a spacer. CONSTITUTION:An ITO film and the like is formed by vacuum-depositing or ion-plating indium oxide or tin oxide and so on, so as to form transparent conductive films 3, 4 on insulating substrates 1, 2, and these transparent conductive films are opposed with each other. The ends of the insulating substrates 1, 2 are adhered to each other for sealing by a sealant 5, and a liquid or a gas 6 is sealed between each insulating substrate 1 and 2. Since the liquid or the gas 6 is placed between each transparent conductive film 3 and 4 instead of a spacer, it is normally insulated, and is electrified only when a touch face for inputting a signal is pushed. When any point on the touch face is pushed, the transparent conductive films 3, 4 can be electrified as the liquid or the gas 6 escapes therefrom, and input error can thus be prevented.

。(Means for Solving Problems) In order to achieve the above object, the present invention provides a transparent touch panel in which insulating substrates with a transparent conductive film laminated on the surface are bonded together, in which liquid or gas is sealed between the insulating substrates. The present invention provides a transparent touch panel characterized by:
