Abstract
A display device includes pixel electrodes that are spaced apart from each other, touch electrodes, each of which forms a capacitance with a finger, which is a position input body performing position input, to detect a position of input by the finger, which is the position input body, a touch line that is sandwiched between adjacent pixel electrodes and is connected to the touch electrodes, and at least two source lines that extend parallel to the touch line. The source lines transmit image signals to the pixel electrodes. The source lines are disposed such that one of the two pixel electrodes is sandwiched between the touch line and one of the two source lines and another one of the two pixel electrodes is sandwiched between another one of the two source lines and the touch line.
