1. A display device with a touch detection function comprising:
a substrate; a display area in which pixels each constituted by a plurality of color regions are arranged in a matrix in a plane parallel to a surface of the substrate; a touch detection electrode that includes a conductive thin wire extending in a plane parallel to the surface of the substrate, the conductive thin wire including a plurality of first thin wire segments each having a linear shape and including a first end and a second end, and a plurality of second thin wire segments each having a linear shape and including a first end and a second end, wherein in adjacent first and second thin wire segments, the second end of the adjacent second thin wire segments and the first end of the adjacent first thin wire segment are connected to each other; a dummy electrode that includes a plurality of third thin wire segments each having a linear shape; and a drive electrode that has electrostatic capacitance with respect to the touch detection electrode, wherein when it is assumed that a direction of arrangement of color regions having the highest human visibility among the color regions is defined as a pixel arrangement direction, that a maximum length of one of the pixels in a pixel orthogonal direction orthogonal to the pixel arrangement direction in the plane parallel to the surface of the substrate is defined as a first unit length, and that a maximum length of one of the pixels in a direction parallel to the pixel arrangement direction is defined as a second unit length, the plurality of first thin wire segments included in the conductive thin wire extend in a direction different from the pixel arrangement direction, and the second end of one of the first thin wire segments is located at a place away from the first end thereof in a direction toward a target position, where the target position is distant from the first end of the first thin wire segment in the pixel orthogonal direction by N times of the first unit length, and is distant from the first end of the first thin wire segment in the pixel arrangement direction by M times of the second unit length, each of N and M is an integer of 2 or larger, and N and M are different from each other, and wherein the plurality of third thin wire segments are arranged parallel to the plurality of first thin wire segments. |
