Abstract

PURPOSE:To constitute the titled input device so that a display of a display device being in the rear of the input device can be looked at distinctly from the front of the input surface, by enclosing a liquid whose refractive index is similar to a refractive index of a resistance sheet, between the resistance sheets. CONSTITUTION:The titled input device is provided with a transparent input surface which has enclosed a liquid having an electric insulating property, having a refractive index being similar to that of a resistance sheet, and having transparency, in a gap between two pieces of resistance sheets. For instance, a resistance sheet base materials 1a, 3a consist of a polyethylene terephthalate film, and an its surface, conductive films 1b, 3b of indium, tin oxide, etc., are vapor- deposited, and the periphery of oil 8b whose refractive index is similar to that of the resistance sheet and which have an electric insulating property is closed up tightly so that this liquid does not leak. In such a way, a reflected light is reduced between an air-gap 8a and the conductive thin films 1b, 3b for reflecting a light beam most greatly on the constitution of this touch type input device, an external light is scarcely reflected and the transmittivity becomes extremely satisfactory.
