Abstract

A touch panel capable of decreasing concavity and convexity generated on the surface and a display unit including the same are provided. The touch panel includes: a first spacer layer on both side faces of a first wiring layer provided on a first transparent substrate; and a second wiring layer on both side faces of a second wiring layer provided on a second transparent substrate. The touch panel also includes a flexible printed circuit board in a gap between the first transparent substrate and the second transparent substrate and in a region including at least part of a region not provided with the adhesion layer in the region opposed to the first wiring layer, the second wiring layer, the first spacer layer, and the second spacer layer.

Dependent claims

A touch panel comprising:

a first transparent substrate and a second transparent substrate arranged in opposition with a gap in between;
a first wiring layer provided on a face of the first transparent substrate facing the second substrate;
a second wiring layer provided on a face of the second transparent substrate facing the first substrate;
a first spacer layer provided on the face of the first substrate facing the second substrate and so as to flank oppositely facing side faces of the first wiring layer;
a second spacer layer provided on the face of the second substrate facing the first substrate and so as to flank oppositely facing side faces of the second wiring layer;
an adhesion layer provided in the gap between the first transparent substrate and the second transparent substrate and in a region between surfaces of the first wiring layer and the first spacer layer respectively facing the second wiring layer and the second spacer layer;
and
a flexible printed circuit board provided in the gap between the first transparent substrate and the second transparent substrate and in a region including at least part of a region not provided with the adhesion layer in the region between the surfaces of the first wiring layer and the first spacer layer respectively facing the second wiring layer and the second spacer layer.
