Abstract

In a touch panel in which lines connected to electrodes used for detecting a touched position are arranged in an area where a touched position can be detected, the accuracy of detection of a touched position is improved. The touch panel includes a substrate; a group of electrode pairs arrayed in a predetermined direction on the substrate; a terminal unit arranged closer to one of ends in the predetermined direction on the substrate, than the group of electrode pairs is; a group of lead-out lines arranged on the substrate, for electrically connecting the group of electrode pairs and the terminal unit; and a control unit electrically connected with the terminal unit, the control unit supplying a signal through the group of lead-out lines to the group of electrode pairs, and detecting an amount of change in charges from each electrode pair. The control unit includes a provisional decision part, and a correction part. The provisional decision part provisionally decides a touched position based on the amount of change in charges. The correction part, using a correction parameter set for an electrode pair at the provisionally decided touched position, corrects an amount of change in charges detected from the electrode pair arranged at a position farther from the terminal unit than the electrode pair at the provisionally decide touched position, in the group of electrode pairs.
