Abstract
A first separate area insulated from a top conductive layer and extending in a direction perpendicular to an extending direction of top electrodes is provided near an inner periphery of a spacer on a surface of the top substrate where the top conductive layer is provided. And/or a second separate area insulated from a bottom conductive layer and extending in a direction perpendicular to an extending direction of bottom electrodes is provided near an inner periphery of the spacer on a surface of the bottom substrate where the bottom conductive layer is provided.
Claims7
A touch panel comprising:
- a top substrate;
- a top conductive layer provided on the top substrate;
- a pair of top electrodes provided on the top substrate and extending from both ends of the top conductive layer;
- a bottom substrate;
- a bottom conductive layer provided on the bottom substrate so as to face the top conductive layer with a prescribed clearance;
- a pair of bottom electrodes provided on the bottom substrate and extending from both ends of the bottom conductive layer in a direction perpendicular to an extending direction of the top electrodes;
- a frame-like spacer formed on peripheries of the top substrate and the bottom substrate therebetween;
- and
- at least one of
- a first separate area insulated from the top conductive layer, the first separate area being provided near an inner periphery of the spacer on a surface of the top substrate, the surface being provided with the top conductive layer, and the first separate area extending to a direction perpendicular to the extending direction of the top electrodes and
- a second separate area insulated from the bottom conductive layer, the second separate area being provided near an inner periphery of the spacer on a surface of the bottom substrate, the surface being provided with the bottom conductive layer, and the second separate area extending to a direction perpendicular to an extending direction of the bottom electrodes.
A manufacturing method of a touch panel, comprising:
- A) bonding a top substrate provided with a top conductive layer and a pair of top electrodes extending from both ends of the top conductive layer and a bottom substrate provided with a bottom conductive layer and a pair of bottom electrodes extending from both ends of the bottom conductive layer such that the top conductive layer faces the bottom conductive layer with a prescribed clearance via a frame-like spacer disposed on peripheries of the top substrate and the bottom substrate therebetween,
- and
- B) forming at least one of
- a first separate area insulated from the top conductive layer, the first separate area being provided near an inner periphery of the spacer on a surface of the top substrate, the surface being provided with the top conductive layer, and the first separate area extending to a direction perpendicular to the extending direction of the top electrodes and
- a second separate area insulated from the bottom conductive layer, the second separate area being provided near an inner periphery of the spacer on a surface of the bottom substrate, the surface being provided with the bottom conductive layer, and the second separate area extending to a direction perpendicular to an extending direction of the bottom electrodes.
