Abstract: Provided is a novel display device which includes a cholesteric liquid crystal and in which a rewritable region and a region capable of retaining display content can coexist. The connection of a capacitor to a liquid crystal element including a cholesteric liquid crystal can be externally controlled, so that display can be maintained or changed. The connection of the capacitor to the liquid crystal element can be controlled using a transistor as a switching element. When a transistor including an oxide semiconductor is used as the transistor, leakage can be reduced and the voltage of the capacitor can be favorably retained.
