  • Patent number: 11119617
    Abstract: A transparent electrode member includes a translucent base, and first transparent electrodes that are arranged side by side in a first direction on a first surface of the base, that are translucent, and that are electrically connected to each other. Each of the first transparent electrodes has a dispersion layer including a matrix composed of an insulating material and conductive nanowires dispersing in the matrix. A coupling member that electrically connects two adjacent first transparent electrodes to each other is composed of a conductive region. The density of the conductive region in peripheral regions of each first transparent electrode is higher than that in a central region of the first transparent electrode.

  • 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.

  • Patent number: 10747383
    Abstract: A transparent electrode member has a transparent base material, a transparent electrode placed on the first surface of the base material, and an insulating layer placed in an insulating region positioned in at least part of the circumference of a region in which the transparent electrode is placed, when viewed from the direction of the normal to the first surface. The transparent electrode has a dispersion layer that includes a matrix composed of an insulating material and also includes conductive nanowires dispersed in the matrix. The transparent electrode also has a region composed of the conductive part and regions composed of optical adjustment parts when viewed from the direction of the normal to the first surface. The conductive region has conductivity higher than the optical adjustment part. In the dispersion layer, the dispersion density of conductive nanowires in the optical adjustment part is lower than that in the conductive part.
