Abstract

A lightweight touch panel is provided. A display panel includes first and second substrates, between which a liquid crystal layer is provided. The first substrate is provided with a pixel electrode, a common electrode, a transistor, and the like of a liquid crystal panel. The second substrate is provided with a touch sensor. The touch sensor includes a first electrode, two second electrodes, a third electrode, and a fourth electrode. The first electrode and the two second electrodes are formed using a first conductive film. The third and fourth electrodes are formed using a second conductive film. The first electrode extends in a first direction. The two second electrodes are provided along a second direction with the first electrode therebetween. The third electrode electrically connects the two second electrodes to each other. The fourth electrode faces the pixel electrode and the common electrode with the liquid crystal layer therebetween.
