Touch panel
First Claim
Patent Images
1. A touch panel comprising:
- a light-transmissive upper substrate formed with an upper conductive layer on a lower surface of the upper substrate;
a light-transmissive lower substrate formed with a lower conductive layer facing the upper conductive layer with an air gap, on a top surface of the lower substrate; and
a bonding layer formed on at least one of inner edges of a lower surface of the upper substrate and a top surface of the lower substrate, and has a first open groove overlapping a second open groove, both the first and the second open grooves communicating with the air gap.

Abstract
The touch panel has a light-transmissive upper substrate, a light-transmissive lower substrate, and a bonding layer. The lower surface of the upper substrate is formed thereon with an upper conductive layer. The top surface of the lower substrate is formed thereon with a lower conductive layer facing the upper conductive layer with an air gap. The bonding layer is formed on at least one of inner edges of the lower surface of the upper substrate and the top surface of the lower substrate, and additionally has an open groove communicating with the air gap. The makeup provides a touch panel reliably operable with a simple structure.
