1. A display device comprising:
a first substrate with a plurality of pixels comprising a display element; and
a second substrate comprising a first conductive layer, a second conductive layer, a third conductive layer, a fourth conductive layer, and a fifth conductive layer,
wherein the first conductive layer is configured to be an antenna capable of transmitting and receiving a radio signal, and comprises a plurality of first openings,
wherein the second conductive layer is configured to be an antenna capable of transmitting and receiving a radio signal, and comprises a plurality of second openings,
wherein the third conductive layer is configured to be an antenna capable of transmitting and receiving a radio signal, and comprises a plurality of third openings,
wherein the fourth conductive layer is configured to be an antenna capable of transmitting and receiving a radio signal, and comprises a plurality of fourth openings,
wherein the fifth conductive layer is not configured to be an antenna capable of transmitting and receiving a radio signal, and comprises a plurality of fifth openings,
wherein the pixels and the first openings each comprise a first region where the pixel and the first opening overlap with each other,
wherein the pixels and the second openings each comprise a second region where the pixel and the second opening overlap with each other,
wherein the pixels and the third openings each comprise a third region where the pixel and the third opening overlap with each other,
wherein the pixels and the fourth openings each comprise a fourth region where the pixel and the fourth opening overlap with each other, and
wherein the pixels and the fifth openings each comprise a fifth region where the pixel and the fifth opening overlap with each other.
