Abstract
A touch panel is made up of (a) an insulating substrate provided with a transparent conductive film, and (b) a flexible insulating substrate provided with a transparent conductive film. A double-sided adhesive tape combines together (a) and (b), between which is provided a spacer. Since the insulating substrate and the flexible insulating substrate are held apart by the spacer, there is a layer of air between the insulating substrate and the flexible insulating substrate. On the two transparent conductive layers are provided anti-reflective films, in the form, for example, of square islets 100 nm thick and with sides of 80 .mu.m, with a pitch Pd of 100 .mu.m and an interval Dw of 20 .mu.m. Instead of providing the anti-reflective films, holes may be selectively provided in the transparent conductive films. In this way, a touch panel can be realized which enables a bright display screen without impairing input sensitivity.
