A liquid ejecting apparatus includes an ejecting unit that includes a piezoelectric element and ejects liquid by driving the piezoelectric element; a first drive circuit that generates a first drive signal; a second drive circuit that generates a second drive signal; and a circuit substrate having one surface on which the first drive circuit is mounted and the other surface on which the second drive circuit is mounted. The first drive circuit includes a first pair of transistors and a second pair of transistors. The second drive circuit includes a third pair of transistors and a fourth pair of transistors. A distance between the first pair of transistors and the third pair of transistors is shorter than a distance between the first pair of transistors and the fourth pair of transistors.
