Patent ID: 7184027

Claim:
A touch panel including a pair of transparent glass substrates each having a transparent conductive film, and arranged in such a fashion as to oppose each other on the side of said transparent conductive films and to be bonded to each other through a seal portion, wherein a thickness of said seal portion is set to be not greater than 5 μm (exclusive of 0); one of said glass substrates has a touch area, and a thickness of said one glass substrate is from 0.3 mm to 0.4 mm; a Young's modulus of said one glass substrate is from 730,000 kgf/cm 2 to 750,000 kgf/cm 2 ; said seal portion is formed of a thermosetting type epoxy resin having a moisture permeability not exceeding 8×10 −12 g·cm/cm 2 ·sec·cmHg when said seal portion is left standing under a condition of 65° C. and 95% RH; said touch panel further includes a wiring portion connected to said transparent conductive film of either one of said pair of glass substrates, and a wiring portion formed on the other of said glass substrates; said touch panel further includes a transfer portion for electrically connecting both of said wiring portions, disposed between both of said wiring portions; said transfer portion is positioned more inward than said seal portion between said pair of glass substrates; and a sum of the thickness t 1 of said transfer portion and both of said wiring portions and a thickness t 2 of said seal portion satisfy the relation t 1 >t 2 .
