A liquid crystal display panel includes a pixel electrode to apply a voltage to a liquid crystal layer disposed between the pixel electrode and an opposed electrode, a thin film transistor connected to the pixel electrode, a scanning line to supply a gate signal to the thin film transistor, a first coordinate detection line disposed parallel to the scanning line, a first coordinate detection electrode formed closer to the liquid crystal layer than the scanning line and the first coordinate detection line, and a first insulating film formed as a layer between the first coordinate detection line and the first coordinate detection electrode. The first insulating film is provided with a contact hole to electrically connect the first coordinate detection line and the first coordinate detection electrode.
