Abstract

Disclosed herein is a capacitive touch panel including: a transparent substrate, a transparent electrode formed on the transparent substrate, the transparent electrode being made of a conductive polymer, a transparent protective layer formed on the transparent electrode, the transparent protective layer having transparent characteristics, and a transparent adhesive formed on the transparent protective layer. According to the present invention, the transparent protective layer is further formed between the transparent electrode and the transparent adhesive to prevent reactivity between the transparent electrode and the transparent adhesive, thereby making it possible to improve operation reliability of the touch panel.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2010-0072064, filed Jul. 26, 2010, entitled "Capacitive Touch Screen," the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a capacitive touch screen. Background technique [0004] With the use of digital technology in more and more computers, computer-aided devices have also been developed, while personal computers, portable transmitters and other personal information processors use various input devices (such as keyboards and mice) ) to perform processing on documents and images. [0005] Although the rapid development of the information society has expanded the use of computers more and more, there has been a problem that it is difficult to operate the product effectively because the keyboard and mouse are currently used as input devices. Therefore, there is an increased demand for...
