The present invention relates to a liquid crystal display panel having a built-in touch screen, and particularly, to a liquid crystal display panel having a built-in touch screen in which photoconductive cells (CDS cells) are arranged on an upper surface of a black matrix to identify the location at which a touch on the liquid crystal display panel occurs. Consequently, a sensor for sensing the location at which a touch on the liquid crystal display panel occurs is prevented from being contaminated or from erroneously operating when broken, which might otherwise occur when the sensor is outwardly exposed, thereby improving the reliability of products, and simplifying manufacturing processes which thus improves productivity.
