A liquid ejecting apparatus includes a first ejecting section that includes a first drive element and ejects liquid by driving the first drive element, a first drive circuit that includes a first transistor and outputs a first drive signal to the first drive element, a second drive circuit that includes a second transistor and outputs a second drive signal to the first drive element, a circuit substrate on which the first drive circuit and the second drive circuit are mounted. The first drive circuit is mounted on a first surface of the circuit substrate, and the second drive circuit is mounted on a second surface of the circuit substrate, and the first transistor and the second transistor are disposed at position that do not overlap one another in plan view of the circuit substrate.
