DISPLAY DEVICE INCLUDING TOUCH SENSOR

摘要

PURPOSE: A display device including a touch sensor is provided to improve contact sensing sensitivity, as including the touch sensor capable of sensing external contact with simple circuit configuration. CONSTITUTION: A first substrate (110) includes a first side able to contact an external object and a second side opposite to the first side. Driving signal lines are located on the second side of the first substrate, and deliver a driving signal to display an image. Pixels include a switching device connected to the driving signal lines, and a sensing signal line (50) is located on the first side or the second side of the first substrate, and delivers a sensing signal by touch. A sensing capacitor (Cm) comprises one driving signal line of the driving signal lines and the sensing signal line.
