Abstract

A display panel capable of sensing a touch pressure may be provided, that includes: a plurality of first electrodes and a plurality of second electrodes which are formed in different layers apart from each other; a plurality of third electrodes formed in the same layer as the layer in which the first electrode is formed; and a reference electrode which is provided between the layer in which the first electrode and the third electrode are formed and the layer in which the second electrode is formed, or provided under the layer in which the first electrode and the third electrode are formed. The plurality of the second electrodes generate a first signal including information on a capacitance which is changed by a touch, and the plurality of the third electrodes generate a second signal including information on a capacitance which is changed by the touch. As a result, it is not necessary to separately provide the touch sensor because the touch position and the touch pressure can be sensed by the display panel. Also, it is possible to simultaneously sense the touch position and the touch pressure instead of to sequentially sense them.
