Claim:
1. A display device equipped with a touch panel configured to detect a touch by an input member, comprising: a display panel unit having a display surface on which the display panel unit displays data; a touch panel unit having a touch panel surface, disposed so as to cover the display surface of the display panel unit; a touch panel controller that detects a touch on the touch panel surface and acquires touch point coordinate information for specifying a location where said touch panel surface is touched; an incline information acquirer that acquires incline information representing an angle of the input member relative to the touch panel surface when the input member contacts the touch panel surface; and a coordinate corrector that, when a line is drawn on the touch panel surface with the input member, corrects the touch point coordinate information in accordance with said incline information, wherein the touch panel unit has X-axis patterned detection electrodes for specifying a location in a first direction where the touch panel surface is touched, Y-axis patterned detection electrodes for specifying a location in a second direction orthogonal to the first direction where the touch panel surface is touched, and bridges that each respectively intersect said X-axis patterned detection electrodes and said Y-axis patterned detection electrodes in a plan view, and wherein the coordinate corrector determines a correction shift amount in accordance with gaps between the bridges and the incline information, and corrects, in accordance with said correction shift amount, the touch point coordinate information from when the line is drawn on the touch panel surface with the input member.
