Abstract
The present invention makes it possible to recognize proximity of a coil without an increase in material cost and production cost. A liquid crystal display panel includes a TFT substrate () and a CF substrate (). A touch panel () includes (i) a plurality of touch sensing electrodes () which are provided on the TFT substrate () so as to detect an electric capacitance between the touch panel () and a subject of a touch or a change in the electric capacitance and (ii) a proximity sensing electrode () which is provided on the CF substrate () so as to detect proximity of a coil ().
