Abstract: According to an aspect, a display device with a touch detection function includes a display area and a touch detection electrode that includes thin wire segments having first and second ends. Thin wire segments include a thin wire segment extending in a direction different from a pixel arrangement direction in which color regions having the highest human visibility are arranged. The second end is located away from the first end in a direction toward a target position that is distant from the first end in a pixel orthogonal direction by N times of a maximum length of one of the pixels in the pixel orthogonal direction, and in the pixel arrangement direction by M times of a maximum length of one of the pixels in the pixel arrangement direction. Each of N and M is an integer of 2 or larger. N and M are different from each other.
