Abstract

A touch screen panel integrated liquid crystal display device in which a mutual capacitive touch screen panel is integrated with a liquid crystal display panel . The device includes a first substrate, a plurality of pixels on the first substrate and including respective pixel electrodes, a second substrate facing the first substrate, a common electrode on a first surface of the second substrate facing the pixel electrodes, a plurality of sensor electrodes on a second surface of the second substrate and including a plurality of transparent pairs extending in a first direction and having a plurality of protrusions extending in a second direction crossing the first direction, and a liquid crystal layer between the substrates, wherein the device senses a touch position by detecting a change of capacitance applied to the sensor electrodes corresponding to an alternating current common voltage applied to the common electrode.
