Abstract:
A novel display panel that is highly convenient or reliable is provided. A pixel circuit includes a first switch, a node, a first capacitor, a second capacitor, and a second switch. The first switch includes a first terminal to which a first signal is supplied and a second terminal electrically connected to the node. The first capacitor includes a first terminal electrically connected to the node. The second capacitor includes a first terminal electrically connected to the node and a second terminal electrically connected to the second switch. The second switch includes a first terminal to which a second signal is supplied and a second terminal electrically connected to the second terminal of the second capacitor. In addition, the second switch has a function of changing from a non-conducting state to a conducting state when the first switch is in a non-conducting state and a function of changing from a conducting state to a non-conducting state when the first switch is in a non-conducting state. The display element performs display on the basis of a potential of the node.
