  • Patent number: 11073953
    Abstract: A transparent electrode member has a transparent electrode layer formed of a dispersion layer which includes a matrix and conductive nanowires dispersed therein to provide an optical adjustment region including a conductive portion having a first dispersion density and an optical adjustment portion having a second dispersion density smaller than the first dispersion density. The transparent electrode layer includes a plurality of first and second electrodes each having the optical adjustment region, and a first wire provided between and electrically connecting two adjacent first electrodes. A region of an insulating layer is formed between the first wire and the second electrodes, and between the first electrodes and the second electrodes. The first wire and a part of the first electrodes in a vicinity of the first wire are formed of a non-adjustment region of the dispersion layer including the conductive portion while lacking the optical adjustment portion.
