Abstract
A liquid crystal display having a touch screen panel (TSP) function includes a sensor unit formed on the first substrate; a first sensor wire disposed on the first substrate and a second sensor wire extending perpendicular to the first sensor wire, wherein the sensor unit includes a first sensor electrode connected to the first sensor wire and a second sensor electrode connected to the second sensor wire, wherein said first sensor electrode and said second sensor electrode connect when touched, and said first and second sensor wires confirm a touch position by transmitting a sensing current through the connection between the first sensor electrode and the second sensor electrode, a trench is formed near the sensor unit and a silicon protrusion pattern to increase the sensitivity of the touch screen panel.
