Abstract
A liquid crystal panel capable of sensing a touch includes a TFT substrate; a CF substratearranged so as to be opposed to the TFT substrate; a liquid crystal layerinterposed between the TFT substrateand the CF substrate; touch drive electrodes Tx arranged on a liquid crystal layerside of the CF substrate; touch detection electrodes Rx arranged on a side of the CF substrateopposite to the liquid crystal layer; a pressing detection electrode Fx arranged on a liquid crystal layerside of the TFT substrate; and a control unit that supplies a driving signal to the touch drive electrodes Tx and detects detection signals output from the touch detection electrodes Rx, thereby detecting a touch position, and that detects amounts of change in electrostatic capacitances generated between the touch drive electrodes Tx and the pressing detection electrode Fx, thereby detecting pressing when touched.
