Abstract

Disclosed herein is a touch panel 100 including: bar type transparent electrodes 120 that are formed on a transparent substrate 110, bar type opening parts 130 that are formed in the bar type transparent electrodes 120 so as to be surrounded by the bar type transparent electrodes 120, and wirings 140 of which one ends are connected to the bar type transparent electrodes 120 and the other ends are collected at one side of the transparent substrate 110. The touch panel 100 includes the bar type transparent electrodes 120 in which the bar type opening parts 130 are formed and subdivides the transparent electrodes, thereby making it possible to improve touch sensitivity without increasing the wirings 140 and improve transparency.

Claims

1. A touch panel,

comprising:

bar type transparent electrodes that are formed on a transparent substrate;

bar type opening parts that are formed in the bar type transparent electrodes so as to be surrounded by the bar type transparent electrodes; and

wirings of which one ends are connected to the bar type transparent electrodes an other ends are collected at one side of the transparent substrate,

wherein two or more bar type opening parts are formed along the width direction of a bar type transparent electrode of the bar type transparent electrodes, and

wherein the bar type transparent electrodes in which the bar type opening parts are formed have a line width below 60 μ

m.

2. A touch panel, comprising:

bar type transparent electrodes that are formed on a transparent substrate;

bar type opening parts that are formed in the bar type transparent electrodes so as to open one ends of the bar type transparent electrodes; and

wirings of which one ends are connected to the bar type transparent electrodes and the other ends are collected at one side of the transparent substrate,

wherein two or more bar type opening parts are formed along the width direction of a bar type transparent electrode of the bar type transparent electrodes.

3. The touch panel as set forth in claim 2, wherein the bar type transparent electrodes in which the bar type opening parts are formed have a constant line width.
