<p>PURPOSE: A display device is provided to include a sun roof on one of two adjacent contact sensors, thereby effectively distinguishing contact and non-contact. CONSTITUTION: A plurality of unit pixels is arranged in a matrix form. The second contact sensor is located around the first contact sensor. A sun roof(204) is located on the second contact sensor. The sun roof changes incident light intensity of the second contact sensor by comparing the incident light intensity of the second contact sensor with the incident light intensity of the first contact sensor. A reader receives/analyzes the first and second signals from the first and second contact sensors.</p>
