## Abstract

A transparent capacitive touch panel comprising a transparent substrate, a transparent cover lens and a transparent adhesive layer is provided, wherein a first transparent electrode layer and a second transparent electrode layer are disposed on the transparent cover lens and the transparent substrate respectively. The transparent adhesive layer is used to bind the first transparent electrode layer and second transparent electrode layer in order to combine the transparent cover lens and the transparent substrate disposed in parallel. Thereby, the manufacturing process of the transparent capacitive touch panel is simplified, and the manufacturing cost of the same is lowered.

## Claims

### Claim 1

A capacitive touch panel, comprising:
a cover lens;
a decoration layer disposed on a surface of the cover lens;
a color filter substrate disposed parallel to the cover lens;
an electrode layer disposed on a surface of the color filter substrate to perform touch-sensing operations, with the surface of the color filter substrate facing the cover lens; and
at least one adhesive layer for binding the cover lens and the color filter substrate.

### Claim 2 (depends on 1)

The capacitive touch panel as recited in claim 1, wherein the adhesive layer is disposed between the cover lens and the electrode layer.

### Claim 3 (depends on 1)

The capacitive touch panel as recited in claim 1, wherein the adhesive layer comprises a double-sided adhesive tape or a liquid-phase adhesive.

### Claim 4 (depends on 1)

The capacitive touch panel as recited in claim 1, wherein the electrode layer is transparent.

### Claim 5 (depends on 1)

The capacitive touch panel as recited in claim 1, further comprising:
an anti-reflection layer disposed on one side of the cover lens facing away from the electrode layer.

### Claim 6 (depends on 1)

The capacitive touch panel as recited in claim 1, wherein the cover lens comprises plastic or glass.

### Claim 7 (depends on 1)
