1. A touch sensor, comprising:
- a base film including a first region and a second region;
first sensing electrode patterns on the first region of the base film, the first sensing electrode patterns consisting of a single layer of a transparent metal oxide; and
second sensing electrode patterns on the second region of the base film, the second sensing electrode patterns including a multi-layered structure that includes a transparent metal oxide pattern and a metal pattern,wherein the first region has greater light transmittance than the second region, and the second region has higher touching sensitivity than the first region; and
each of the first sensing electrode patterns and the second sensing electrode patterns has first patterns and second patterns that are insulated from the first patterns, and the first patterns and the second patterns are arranged in directions crossing each other.

Abstract
A touch sensor includes a base film including a first region and a second region. First sensing electrode patterns are formed on the first region of the base film. The first sensing electrode pattern may consist of a transparent metal oxide. Second sensing electrode patterns are formed on the second region of the base film. The second sensing electrode pattern may include a multi-layered structure that includes a transparent metal oxide pattern and a metal pattern.

14. A method of manufacturing a touch sensor, comprising:
-
preparing a base film including a first region and a second region; forming a first transparent metal oxide layer on the base film; forming a low resistance pattern on a portion of the first transparent metal oxide layer on the second region, the low resistance pattern having a resistance less than that of the first transparent metal oxide layer; etching the first transparent metal oxide layer using the low resistance pattern as a mask to form a second sensing electrode pattern including the low resistance pattern on the second region; and forming a first sensing electrode pattern consisting of a transparent metal oxide on a portion of the base film of the first region. - View Dependent Claims (15, 16, 17, 18, 19, 20)
