1. A touch panel comprising:

  • a first substrate;

    a second substrate;

    a liquid crystal layer;

    a pixel electrode;

    a common electrode; and

    a touch sensor comprising a first electrode, two second electrodes, a third electrode, and a fourth electrode,wherein the first substrate and the second substrate face each other,wherein the liquid crystal layer is provided between the first substrate and the second substrate,wherein the first substrate is provided with the pixel electrode and the common electrode,wherein alignment of the liquid crystal layer is controlled by an electric field between the pixel electrode and the common electrode,wherein the second substrate is provided with the touch sensor,wherein the first electrode and the two second electrodes are formed using a first conductive film,wherein the third electrode and the fourth electrode are formed using a second conductive film,wherein the first electrode and the two second electrodes are each a mesh electrode having a plurality of openings,wherein the first electrode extends in a first direction,wherein the two second electrodes are provided along a second direction with the first electrode therebetween,wherein the two second electrodes are electrically connected to each other by the third electrode,wherein the third electrode comprises a region overlapping with the first electrode, andwherein the fourth electrode is provided to face the pixel electrode and the common electrode with the liquid crystal layer therebetween.
