Touch panel and method for producing same
A touch panel includes a first planar body having a first electrode patterned on one surface of a first substrate and a first lead-out wiring electrically connected to the first electrode, a cover sheet, a second planar body provided between the first planar body and the cover sheet except a predetermined region of a side edge of the first substrate, and a flexible wiring board interposed at a gap portion formed between the predetermined region of the side edge of the first substrate and the cover sheet, wherein the flexible wiring board includes a connector portion fixed onto the connection terminal of the first lead-out wiring held by the first planar body and electrically connected with the first lead-out wiring, and a spacer member that abuts with both the connector portion and the cover sheet is disposed between the connector portion and the cover sheet.
1. A touch panel comprising:
a first planar body having a first electrode patterned on one surface of a first substrate and a first lead-out wiring electrically connected to the first electrode;
a cover sheet provided on one surface side of the first planar body;
a second planar body provided between the first planar body and the cover sheet except a predetermined region of a side edge of the first substrate, the predetermined region in which one end portion of the first lead-out wiring serving as a connection terminal is disposed; and
a flexible wiring board interposed at a gap portion formed between the predetermined region of the side edge of the first substrate and the cover sheet, and drawn outside from a side of the first planar body and the cover sheet, wherein
the flexible wiring board includes a connector portion fixed onto the connection terminal of the first lead-out wiring held by the first planar body and electrically connected with the first lead-out wiring,
a spacer member that abuts with both the connector portion and the cover sheet is disposed between the connector portion and the cover sheet, and
the spacer member is disposed by being fixed to only one of the cover sheet and the connector portion.
2. The touch panel according to claim 1 , wherein the spacer member is a film body disposed on the connector portion.
3. The touch panel according to claim 1 , wherein the spacer member is formed of an ultraviolet curing resin.
4. The touch panel according to claim 1 , wherein a width of the spacer member is formed larger than a width of the connector portion of the flexible wiring board in a plan view.
5. A method for manufacturing a touch panel comprising:
a planar body adhering step of adhering a first planar body, which has a first electrode patterned on one surface of a first substrate and a first lead-out wiring electrically connected to the first electrode, and a second planar body with an adhesive layer therebetween, in a state of exposing a predetermined region of a side edge of the first substrate, the predetermined region in which one end portion of the first lead-out wiring serving as a connection terminal is disposed;
a flexible wiring board connecting step of connecting a connector portion of a flexible wiring board onto the connection terminal of the first lead-out wiring held by the first planar body;
a spacer adhering step of laminating and adhering a spacer member on an upper side of the connector portion connected onto the connection terminal of the first lead-out wiring; and
a cover sheet adhering step of laminating and adhering a cover sheet on an upper side of the second planar body and the spacer member, after interposing an adhesive layer on an exposed surface of the second planar body such that the spacer member is not fixed to the cover sheet.
