A thin film circuit includes a thin film switching circuit with an upper circuit layer including at least one upper joint, and a lower circuit layer including at least one lower joint corresponding to the upper joint. The lower circuit layer is set under the upper layer, and an air-filled space is disposed between the upper joint and the lower joint. The thin film switching circuit further includes at least one first air conduit set between the upper circuit layer and the lower circuit layer and connected to the air-filled space, and at least one bus structure connected to the thin film switching circuit and extending out of the thin film switching circuit to transmit electrical signals of the thin film switching circuit. The bus structure includes at least one second air conduit. One end of the second air conduit is connected to ambient atmosphere, and the other end of the second air conduit is connected to the first air conduit so that the air in the air-filled space can flow in and out to the ambient atmosphere through the first air conduit and the second air conduit.
