TRANSPARENT ELECTRODE MEMBER, ELECTROSTATIC CAPACITANCE-TYPE SENSOR, AND INPUT/OUTPUT DEVICE

WIPO Patent Application WO/2021/019823

A1

A transparent electrode member according to one aspect of the present invention is provided with: an insulative base material having translucent property; a plurality of transparent electrodes that have a translucent property and are disposed on a first surface which is one surface of the base material; and an insulating layer formed between the transparent electrodes. Each of the transparent electrodes is provided with a dispersion layer including a matrix formed from an insulating material and conductive nanowires dispersed in the matrix. The transparent electrode has a conductive region comprising a conductive part and has an optical adjustment region having an optical adjustment part. The conductive part has an electric conductivity higher than that of the optical adjustment part. The dispersion density of the conductive nanowires in the dispersion layer is lower in the optical adjustment part than in the conductive part. The optical adjustment region has a plurality of partial regions disposed at positions corresponding to grid points of grids along the in-plane of the transparent electrode. In a rectangular area formed by defining the corners thereof with four adjacent grid points, among the plurality of grid points, the two diagonal lines of the rectangular area are different in length, and thus, invisibility of the pattern of the transparent electrode can be improved and generation of moire can be suppressed.
