Abstract
To provide a low-cost display device which can accurately detect a position touched by a finger. A display device displays an image by having display elements capable of performing electro-optic responses formed between conductible first and second substrates, and detects a contact position touched by a contact body by having a conductive impedance surface formed on the second substrate side. The display device includes: linearization pattern sections formed on the first substrate, which include a plurality of electrodes capable of detecting electric currents on a conductive impedance surface; and a conductive member which electrically connects the linearization pattern sections with the conductive impedance surface on the second substrate.
