Display device with touch detection function and electronic apparatus

摘要

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.

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 thin wire segments each having a linear shape and including a first end and a second end, the second end of one of adjacent thin wire segments and the first end of the other of the adjacent thin wire segments being connected to each other; a drive electrode that has electrostatic capacitance with respect to the touch detection electrode; and a display function layer having a function of displaying an image in the display area, 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 thin wire segments included in the conductive thin wire include a thin wire segment extending in a direction different from the pixel arrangement direction, and the second end of the thin wire segment is located at a place away from the first end in a direction toward a target position, where the target position is distant from the first end of the 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 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.
