Abstract
There is provided a highly reliable screen input type display device using a touch panel which can facilitate the control of a gap formed between upper and lower substrates and can stabilize the linearity of the resistance value detection of a resistance film, whereby an erroneous detection of coordinated can be eliminated. For this purpose, a tape-like conductive pressure sensitive adhesive member, which is formed by sandwiching a metal foil with conductive pressure sensitive adhesive material, is used at a connection portion between an upper wiring electrode mounted on an upper resistance film formed on an upper substrate and an inter-substrate connection wiring electrode formed on a lower substrate.
