Screen input type display device
First Claim
1. A screen input type display device which arranges a touch panel on a display surface of a display device, the touch panel comprising:
- a first substrate having a first resistance film, a second substrate having a second resistance film, an inter-substrate connection wiring electrode being formed on the second substrate, and a conductive pressure sensitive adhesive member being disposed between the first resistance film and the inter-substrate connection wiring electrode, the conductive pressure sensitive adhesive member electrically connecting the first resistance film and the inter-substrate connection wiring electrode, and the conductive pressure sensitive adhesive member having pressure sensitive adhesive material in which conductive particles are mixed formed on both surfaces of a metal foil for laminating the first substrate and the second substrate.

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.
