<p><P>PROBLEM TO BE SOLVED: To provide a capacitance type liquid crystal display device with a touch panel, wherein malfunction by noise from the liquid crystal display device is suppressed when the touch panel and liquid crystal display device are used in an approaching state. <P>SOLUTION: The capacitance type liquid crystal display device with the touch panel includes a liquid crystal display panel 11 and the touch panel 12 that is stacked on the liquid crystal display panel 11 and has a plurality of detection electrodes 15. On the non-display region side of the liquid crystal display panel 11, wires are laid along the periphery of a display region and a wire NDL for noise detection where both ends are opened is formed. A noise output circuit 40 is connected to the wire NDL for noise detection. A coordinate detecting circuit (touch panel controller 36) includes a noise removal circuit for calculating the difference between the outputs of a capacity detection circuit and the noise output circuit. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
