Abstract: A display apparatus according to one embodiment comprises pixels each comprising a liquid crystal display element (LC element) and an organic EL display element (EL element). The EL element comprises an anode and a cathode electrically separated from each electrode of the LC element. Each pixel comprises a first transistor which changes the magnitude of a current flowing through the EL element based on the potential of a first bus line; a second transistor which electrically separates the first bus line and the LC element; and a third transistor which electrically connects the first and second transistor with the first bus line.
