## Abstract

Disclosed herein are a touch sensor and a method for manufacturing the same. The touch sensor includes a window substrate, an electrode unit integrally formed on one side surface of the window substrate, an inorganic insulating layer coating the electrode unit, and a chemically strengthened layer formed on the other side surfaces of the window substrate except for the one side surface of the window substrate.

## Claims

### Claim 1

A touch sensor, comprising:
a window substrate;
an electrode unit formed on one side surface of the window substrate; and
a chemically strengthened layer formed on the other side surfaces of the window substrate except for the one side surface.

### Claim 2 (depends on 1)

The touch sensor as set forth in claim 1, wherein the electrode unit includes an electrode pattern formed on the one side surface of the window substrate, and an insulating layer coating the electrode pattern.

### Claim 3 (depends on 2)

The touch sensor as set forth in claim 2, wherein the insulating layer is made of an inorganic material.

### Claim 4 (depends on 3)

The touch sensor as set forth in claim 3, wherein the inorganic material is made of silicon dioxide or silicon alkoxide.

### Claim 5 (depends on 1)

The touch sensor as set forth in claim 1, wherein the chemically strengthened layer is formed on the one side surface of the window substrate, and an upper surface or a lower surface of the window substrate.

### Claim 6

A method for manufacturing a touch sensor, comprising:
forming a plurality of electrode units on one side surface of a window substrate;
cutting the window substrate and the plurality of electrode units so that the plurality of electrode units are respectively separated; and
forming a chemically strengthened layer by performing chemical strengthening on the other side surfaces of the window substrate except for the one side surface through a chemically strengthening agent.

### Claim 7 (depends on 6)

The method as set forth in claim 6, wherein the forming of the plurality of electrode units includes patterning an electrode and forming an electrode pattern, and coating the electrode pattern with an inorganic material and forming an insulating layer.

### Claim 8 (depends on 7)

The method as set forth in claim 7, wherein the inorganic material is made of silicon dioxide or silicon alkoxide.

### Claim 9 (depends on 6)

The method as set forth in claim 6, wherein the chemically strengthening agent is made of potassium nitrate.

### Claim 10 (depends on 6)

The method as set forth in claim 6, wherein the chemically strengthened layer is formed on the one side surface of the window substrate, and an upper surface or a lower surface of the window substrate.
