Abstract
An IPS-LCD panel includes first and second substrates, and a liquid crystal interposed therebetween. An electro-conductive polarizer is formed on the second substrate of the IPS-LCD panel, and a ground electrode surrounds the electro-conductive polarizer. The electro-conductive polarizer and ground electrode prevent exterior static electricity from affecting the liquid crystal layer.
