Abstract
A display panel includes an array substrate and an opposite substrate. The array substrate includes pixels, first signal lines, and second signal lines. The opposite substrate is combined with the array substrate, interposing a liquid crystal layer there between. The opposite substrate includes an opposite base substrate and first and second protruded electrodes. The first and second protruded electrodes are formed in regions corresponding to the first and second signal lines, respectively, and are electrically connected to the first and second signal lines, respectively, based on an externally provided pressure. Therefore, a thickness of the display panel is decreased, and a touch position is easily detected.
