Abstract
An array substrate includes gate lines, source lines, switching components, position detecting electrodes, a light blocking portion, and position detecting lines. The position detecting electrodes are disposed in a layer lower than the gate lines and the source lines to detect input positions at which the position input operation is performed with a position input body based on electrostatic capacitances between the position input body and the position detecting electrodes. The light blocking portion is disposed in a layer lower than channel regions of the switching components and opposite the channel regions with a lower insulating film between the light blocking portion and the channel regions. The position detecting lines are formed from sections of a conductive film from which the light blocking portion is formed and coupled to the position detecting electrodes.
