(detailed structure of touch panel 1)
In the touch panel 1 of the manner, its input area 100a possesses resistive film type input area 101 and the capacitance type input area 102 that the following describes, and such resistive film type input area 101 and capacitance type input area 102 are configured in to be overlooked on the position of staggering.
In the manner, touch panel 1 possesses: the 2nd substrate 20 of the 1st substrate 10 of the light transmission that is made of glass plate, plastic plate etc. and the light transmission that is made of glass plate, plastic plate etc., and in the manner, all use glass plate for any one of the 1st substrate 10 and the 2nd substrate 20.At this, the 1st substrate 10 and the 2nd substrate 20, with between the 1st 11,21 across the relative mode of predetermined gap, utilize the encapsulant 31 of frame shape to be glued together.The 2nd substrate 20 is configured in the input operation side, and the 1st substrate 10 is configured in a side of liquid-crystal apparatus 5.Therefore, the 2nd 22 of the 2nd substrate 20 towards the input operation side, the 2nd 12 side towards liquid-crystal apparatus 5 of the 1st substrate 10.In the touch panel 1 that constitutes like this, when importing on resistive film type input area 101, the 2nd substrate 20 needs bending.Therefore, the thickness of the 2nd substrate 20 to the 1 substrates 10 is thin, and possesses flexible.
On the 1st 11 of the 1st substrate 10, the zone 13 of stretching out of stretching out at the edge from the 2nd substrate 20 is connected with flexible substrate 33.Such flexible substrate 33 is to be used for from resistive film type input area 101 and the capacitance type input area 102 shared wiring part to external output signal.
Encapsulant 31 possesses along the outer peripheral outer frame part 31a of the 2nd substrate 20 with near the partition frame part 31b between the fillet centre on the 2 relative limits of outer frame part 31a, becomes input area 100a with the roughly integral body of encapsulant 31 area surrounded.In addition, input area 100a with respect to partition frame part 31b one side's side (with a side that is connected with flexible substrate 33 away from a side) become resistive film type input area 101, on the other hand, opposite side (being connected with a side of flexible substrate 33) becomes capacitance type input area 102.
In touch panel 1, at resistive film type input area 101, on the 1st 11 of the 1st substrate 10, be formed with (Indium Tin Oxide: the 1st electrode 15 of the light transmission of film formation tin indium oxide) by ITO, be formed with the 2nd electrode 25 of the light transmission that is made of the ITO film on the 1st 21 of the 2nd substrate 20, its inboard becomes air layer.
On the 1st 11 of the 1st substrate 10, be formed with wiring pattern (not shown) from the 1st electrode 15 to stretching out zone 13, utilize such wiring pattern, can be from the 1st electrode 15 to flexible substrate 33 output signals.In addition, in encapsulant 31, be mixed with conductive material 30 between substrate, conductive material 30 is made of plastic bead that is formed with metal level on the surface etc. between substrate, and conductive material 30 is between between the 1st 21 of the 1st the 11 and the 2nd substrate 20 of the 1st substrate 10 between substrate, thereby the 2nd electrode 25 that will be formed on the 1st 21 of the 2nd substrate 20 is connected with wiring pattern (not shown) conduction on being formed on the 1st 11 of the 1st substrate 10.Utilize conductive material 30 and wiring pattern between such substrate, can be from the 2nd electrode 25 to flexible substrate 33 output signals.
In the resistive film input area 101 that constitutes like this, when the 2nd substrate 20 is pressed, because the 1st electrode 15 contacts with the 2nd electrode 25 at the pressing position place, so, detect input coordinate by detecting its contact position.Thereby, at resistive film input area 101,, can carry out the input of information by the regulation zone of pushing the 2nd substrate 20 with finger, pen etc.

Fig. 4 is the key diagram of cross-section structure of display device 100 of schematically representing the tape input function of embodiments of the present invention 3.And, because the basic structure of the manner is identical with embodiment 1,2, thus illustrate for the identical identical label of part mark, and omit their explanation.
As shown in Figure 4, the display device 100 of the tape input function of the manner, also same with embodiment 1,2, have liquid-crystal apparatus 5 and the overlay configuration touch panel 1 on the face of a side of the ejaculation display light of this liquid-crystal apparatus 5.In addition, in touch panel 1, its input area 100a possesses resistive film type input area 101 and the capacitance type input area 102 that the following describes, and such Resistance model for prediction input area 101 and capacitance type input area 102 are configured in to be overlooked on the position of staggering.
In the manner, also same with embodiment 1,2, resistive film type input area 101 at touch panel 1, on the 1st 11 of the 1st substrate 10, be formed with the 1st electrode 15 of the light transmission that constitutes by the ITO film, be formed with the 2nd electrode 25 of the light transmission that is made of the ITO film on the 1st 21 of the 2nd substrate 20, its inboard becomes air layer.In addition, be blended in conductive material 30 between the substrate in the encapsulant 31, between between the 1st 21 of the 1st the 11 and the 2nd substrate 20 of the 1st substrate 10, thereby the 2nd electrode 25 on the 1st 21 that is formed on the 2nd substrate 20 is connected with wiring pattern (not shown) conduction on being formed on the 1st 11 of the 1st substrate 10, utilize conductive material 30 and wiring pattern between such substrate, can be from the 2nd electrode 25 to flexible substrate 33 output signals.
In the manner, same with embodiment 2 at capacitance type input area 102, the 3rd electrode 18,19 of light transmission is formed on the 1st of the 2nd substrate 20.But, be blended in conductive material 30 between the substrate in the encapsulant 31, between between the 1st 21 of the 1st the 11 and the 2nd substrate 20 of the 1st substrate 10, thereby the 3rd electrode 18,19 on the 1st 21 that is formed on the 2nd substrate 20 is connected with wiring pattern (not shown) conduction on being formed on the 1st 11 of the 1st substrate 10, utilize conductive material 30 and wiring pattern between such substrate, can be from the 3rd electrode 18,19 to flexible substrate 33 output signals.In addition, at capacitance type input area 102, on the 1st 11 of the 1st substrate 10, be formed with the shielding layer 16 of the light transmission that constitutes by the ITO film.

And then, because both sides at capacitance type input area 102 and resistive film input area 101, can watch the image that shows at liquid-crystal apparatus 5 from the input operation side, so on any one of capacitance type input area 102 and resistive film input area 101, can both the limit watch on the image limit that liquid-crystal apparatus 5 shows and carry out the input of information from the input operation side.Under these circumstances, also, between the 1st substrate 10 and the 2nd substrate 20, be filled with the high-index material 14 of insulativity, so because there is not reflexive interface, so can show bright image owing at capacitance type input area 102.
