Light-transmitting metal electrode, electronic apparatus and light emitting device

An electronic apparatus comprising:

• a structure body having a major surface;
• and
• a metal layer provided on the major surface and including a metal nanowire and a plurality of openings formed with the metal thin layer,
• the metal nanowire including a plurality of first straight line parts along a first direction parallel to the major surface, and a plurality of second straight line parts along a direction parallel to the major surface, and different from and intersecting the first direction,
• a maximum length of the first straight line parts along the first direction and a maximum length of the second straight line parts along the direction different from the first direction, are not more than a wavelength of visible light,
• a ratio of an area of the metal nanowire viewed in a normal direction of the major surface to an area of the metal layer viewed in the normal direction vertical to the major surface being more than 20% and not more than 80%, and
• the metal layer being used as an electrode in the structure.

A light emitting device comprising:

• an optical member having a light transmitting part and a major surface, and
• a metal layer provided on the major surface and including a metal nanowire and a plurality of openings formed with the metal nanowire,
• the metal thin layer including a plurality of first straight line parts along a first direction parallel to the major surface, and a plurality of second straight line parts along a direction parallel to the major surface, and different from and intersecting the first direction;
• a maximum length of the plurality of first straight line parts along the first direction and a maximum length of the second straight line parts along the direction different from the first direction being not more than a wavelength of visible light, and
• a ratio of an area of the metal nanowire viewed in a normal direction to an area of the metal layer viewed in the normal direction of the major surface being more than 20% and not more than 80%.
