Abstract
A display device with a novel structure is provided. The display device includes a first substrate provided with a plurality of pixels including a display element, and a second substrate including a first conductive layer provided with a plurality of first openings. The first conductive layer has a function of an antenna capable of transmitting and receiving a radio signal. The pixel and the first opening include a region where the pixel and the first opening overlap with each other. The second substrate includes an element layer. The element layer includes a transistor. The transistor has a function of an amplifier capable of amplifying the radio signal. The transistor each includes a semiconductor layer including a metal oxide in a channel formation region. The metal oxide contains In, Ga, and Zn.
