1. A touch panel, comprising:
- a flexible substrate; and
a plurality of touch sensors formed over the flexible substrate, wherein each of the touch sensors includes;
a first conductive pattern;
a second conductive pattern at least partially overlapping the first conductive pattern; and
an insulating layer interposed between and electrically insulating the first and second conductive patterns,wherein the insulating layer is formed at least in part of an elastic material, andwherein the distance between the first and second conductive patterns is configured to vary as the flexible substrate is bent.

Abstract
A touch panel and manufacturing method thereof are disclosed. In one aspect, the touch panel includes a flexible substrate and a plurality of touch sensors formed over the flexible substrate. Each of the touch sensors includes a first conductive pattern, a second conductive pattern at least partially overlapping the first conductive pattern, and an insulating layer interposed between and electrically insulating the first and second conductive patterns. The insulating layer is formed at least in part of an elastic material and the distance between the first and second conductive patterns is configured to vary as the flexible substrate is bent.
