With objectives of providing a transparent board with conductive multi-layer antireflection, under condition of high transmissivity not only on a glass substrate but also on a non-glass transparent substrate with property of conductivity and demanded resistance at most exterior surface, laminating at least three layer thin films on a transparent substrate provides with an effect of high transmissivity by suppressing reflection from interference of optical waves, in which the transparent first dielectric layer thin film on the substrate that has a higher refractive index than the substrate has, the transparent second dielectric layer thin film next to the first-layer film that has a lower refractive index than the substrate has, and the most exterior transparent third conductive-layer thin film.

Transparent board with conductive multi-layer antireflection films, transparent touch panel using this transparent board with multi-layer antireflection films, and electronic equipment with this transparent touch panel

A touch panel switch having a wide usable operating range and thus a large effective use area and having electrodes disposed opposedly to each other through a spacer installed around the periphery thereof, the spacer formed in an elastic body of 1&times;10 to 1&times;10 dyne/cm in elastic modulus comprising an insulation layer and an adhesive layer, the insulation layer further comprising a clearance holding part with a uniform thickness and a gradient part with a thickness gradually decreasing from the clearance holding part into a substrate having the electrodes formed thereon.

Touch panel switch

With objectives of providing with a transparent board with conductive multi-layer antireflection thin films, under condition of high transmissivity not only on a glass substrate but also on a non-glass transparent substrate with property of demanded electrical resistance at the most exterior surface, this invention laminates at least three layers of thin films on a transparent substrate, in which the transparent dielectric 1 -layer thin film on the substrate that has a higher refractive index than the substrate has, the transparent dielectric 2 -layer thin film next to the 1st layer that has a lower refractive index than the substrate has, and the most exterior transparent conductive transparent thin film that includes weight percentage no less than 20% of SnO .

TRANSPARENT SUBSTRATE WITH CONDUCTIVE MULTILAYER ANTI REFLECTION FILM, TRANSPARENT TOUCH PANEL USING THE TRANSPARENT SUBSTRATE WITH MULTILAYER ANTI REFLECTION FILM AND ELECTRONIC APPARATUS USING THE TOUCH PANEL

A touch panel has excellent visibility and little waviness on respective elements even if the touch panel is exposed in a severe temperature or moisture environment. The touch panel includes an upper electrode sheet and a lower electrode board having respective transparent electrodes face to each other, and both of the sheet and the board are made of respective materials containing an identical main component to each other. In the touch panel, differences in dimensional changes due to the severe environment are restrained so as to be small. Therefore, waviness on the upper electrode sheet and warp of the lower electrode board scarcely occur, and the touch panel can maintain excellent visibility.
