1. Field
The embodiment relates to a touch panel.
2. Background
An input function through a touch of an image displayed on a touch panel by an input device such as a stylus pen or a finger has been applied to various electronic appliances. Various types of touch panels may be provided depending on positions of transparent electrodes formed in the touch panels. For example, the transparent electrode may be directly formed on a cover substrate.
A printing layer is formed in a Bezel area where a touch is not sensed, and a wire electrode is formed on the printing layer. The wire electrode may be connected with a sensing electrode to sense the touch through a pad part. As at least two printing layers are formed, a step difference may be formed between the printing layers or between the printing layer and a cover window. The wire electrode may be formed on the printing layers having the step difference. Accordingly, the wire electrode may be cracked or the reliability of the wire electrode may be degraded due to the step difference. In addition, if the wire electrode is directly formed on the printing layer, the wire electrode may be damaged due to the high surface roughness of the printing layer when the wire electrode is formed.
