Touch panel including a wiring substrate disposed between a pair of substrates and a method for producing the same

摘要

A touch panel and a method of producing the touch panel are provided in which a touch panel having a gap between two transparent substrates that is uniform in a plane can stably be obtained by setting a gap between the two transparent substrates in an area where a wiring substrate is disposed to a desired gap. A touch panel includes a pair of transparent substrates opposed to and away from each other and connection terminals provided on at least one of opposed surfaces of the pair of transparent substrates. A wiring substrate that is disposed between the pair of transparent substrates and has one surface electrically connected to the connection terminals and the other surface disposed away from one of the transparent substrates opposed to the other transparent substrate on which the connection terminals are provided. An insulating layer provided in a gap between the pair of transparent substrates in an area where the wiring substrate is disposed in a state where the wiring substrate and the connection terminals are connected.

1. A touch panel comprising:
first and second transparent substrates positioned opposed to and away from each other, each transparent substrate having opposed first and second surfaces respectively; a resistive film formed on an input area of each of the first and second transparent substrates; first opposed electrodes formed on the first transparent substrate and second opposed electrodes formed on the second transparent substrate, the first opposed electrodes and second opposed electrodes being connected to opposed sides of the respective resistive film; first connection terminals provided on the second surface of the first transparent substrate facing the second transparent substrate at terminal ends of the first opposed electrodes, and second connection terminals provided on the first surface of the second transparent substrate facing the first transparent substrate at terminal ends of the second opposed electrodes; a wiring substrate that is disposed between the first and second transparent substrates and has a first wiring substrate surface electrically connected to the second connection terminals, and a second wiring substrate surface opposed to the first wiring substrate surface and electrically connected to the first connection terminals; and an insulating layer filled in gaps between the first wiring substrate surface and the first substrate and between the second wiring substrate surface and the second substrate, wherein the insulating material is provided between the first and second substrates to connect the first substrate to the second substrate, and to connect the wiring substrate to the first connection terminals and the second terminals.
