摘要：
A liquid crystal display panel in which coordinate detection electrodes are formed on a first substrate and protruding contact portions are formed on a second substrate as a touch panel function includes a conversion circuit formed therein. The conversion circuit subjects information indicative of whether the protruding contact portions are in contact with the coordinate detection electrodes to parallel/serial conversion to output the converted information to the coordinate detection circuit.
