A touch panel includes a first substrate having a first conductive layer on one surface; a second substrate having a second conductive layer on a surface on a side facing the first conductive layer; a plurality of first electrodes extending from the first conductive layer; and a plurality of second electrodes extending from the second conductive layer. The first conductive layer is formed of a plurality of parallel strips; and the plurality of first electrodes are formed of a straight portion extending in a predetermined direction, and an inclined portion coupled to the straight portion by being inclined by a predetermined angle with respect to a direction orthogonal to the straight portion. Fading, thickness variation and the like at the time of printing can be prevented and fine patterning can be easily carried out, so that an inexpensive touch panel in which overall miniaturization is achieved can be obtained.

The invention relates to touch panels for use in a variety of electronic apparatuses, and designed to prevent separation of a lower substrate and an antireflection layer, and to ensure reliable operation. An undercoat layer () made of any of silicon oxide and a compound having a principal ingredient of silicon oxide is disposed between the antireflection layer () and the lower substrate () made of glass having the same principal ingredient of silicon oxide, to improve strength of adhesion between the lower substrate () and the antireflection layer (), thereby preventing separation of the antireflection layer () from the lower substrate (), and providing the touch panel with reliable operation.

An upper substrate that has upper conductive layer formed on a bottom surface thereof, is bonded to lower substrate, that has lower conductive layer opposed to the upper conductive layer with a predetermined space held therebetween, on a top surface of lower substrate by an adhesive layer that is made of a thermoplastic resin containing a tackifier dispersed therein, with a bonding property of the adhesive layer being enhanced by pressing. Addition of the tackifier increases flexibility of the adhesive layer and performs bonding with a large adhesive area at pressing. Thus, a width of the adhesive layer can be as small as approximately 1 to 1.5 mm. This can provide a smaller touch panel ensuring a predetermined touch sensitive area.

A transparent touch panel is structured by forming connecting layers that contain conductive metal powder dispersed in a resin, on ends of wiring patterns on a wiring board to which upper electrodes and lower electrodes are to be bonded. This structure can provide a transparent touch panel that ensures bonding of upper and lower substrates and the wiring board and stable electrical connection.

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.

A transparent touch panel (TTP) comprising a fixed substrate of transparent resin, an adhesion layer disposed on the fixed substrate, an antireflection layer disposed on the adhesion layer, a first transparent conductive layer disposed on the antireflection layer, a second transparent conductive layer opposed to and spaced apart from the first transparent conductive layer, and a flexible transparent film disposed on the upper surface of the second transparent conductive layer. In one embodiment, rather than having a separate adhesion layer and antireflection layer, the adhesion layer may also serve as the antireflection layer, the rest of the above components remaining the same. The use of transparent resin in the TTP of the present invention reduces weight and increases resistance to breaking. The antireflection layer decreases the light reflection at respective boundary surfaces, thus increasing light transmittance. The adhesion layer strengthens adhesion of the antireflection layer and the first transparent conductive layer onto the fixed substrate, thus providing for even and uniform electrical resistance in the transparent conductive layer. An electronic apparatus thus comprises at least a control circuit, an LCD device for display, and a TTP disposed on the display surface of the LCD device. The TTP may comprise the TTP described above and/or may comprise a polarizing plate on an operating surface of the transparent touch panel.
