Wiring board, module, and image display apparatus

A wiring board comprising:

• a substrate that has a first surface and a second surface that is opposite the first surface;
• and
• a mesh wiring layer that is disposed on the first surface of the substrate,
• wherein the wiring board has an electromagnetic wave transceiver function,
• wherein the substrate is transparent,
• wherein the mesh wiring layer serves as an antenna and includes a wiring line,
• wherein two or more opening portions are formed by being surrounded by the wiring line,
• wherein a planar shape of each of the opening portions is a polygonal shape that has opposing sides parallel with each other, and
• wherein 95% or more opening portions among 100 opening portions or all of the opening portions
• satisfy a relationship of
• 0.70D≤d≤0.98D or
• satisfy a relationship of
• 1.02D≤d≤1.30D, where
• d is distances between sides that extend in a first direction regarding the opening portions, and
• D is an average value of the distances between the sides that extend in the first direction regarding the 100 opening portions continuously adjacent to each other or all of the opening portions.

A wiring board comprising:

• a substrate that has a first surface and a second surface that is opposite the first surface;
• a mesh wiring layer that is disposed on the first surface of the substrate;
• and
• a power supply portion that is electrically connected to the mesh wiring layer,
• wherein the substrate is transparent,
• wherein the mesh wiring layer includes a transmission portion that is connected to the power supply portion and a transceiver portion that is connected to the transmission portion,
• wherein the mesh wiring layer includes a wiring line that serves as the transmission portion and the transceiver portion,
• wherein two or more opening portions are formed by being surrounded by the wiring line,
• wherein a planar shape of each of the opening portions is a polygonal shape that has opposing sides parallel with each other, and
• wherein 95% or more opening portions among 100 opening portions or all of the opening portions
• satisfy a relationship of
