1. A liquid discharge device comprising:
a discharge head that discharges a liquid in response to a drive of a first piezoelectric element;
a substrate that includes a first through-hole;
a first drive circuit, a second drive circuit, and a third drive circuit provided on the substrate;
a metal frame attached to the substrate; and
a first screw that is inserted through the first through-hole and attaches the metal frame to the substrate, wherein
the first drive circuit outputs a first drive signal for driving the first piezoelectric element so that the discharge head discharges a liquid having a first discharge amount,
the second drive circuit outputs a second drive signal for driving the first piezoelectric element so that the discharge head discharges a liquid having a second discharge amount,
the third drive circuit outputs a third drive signal for driving the first piezoelectric element so that the discharge head does not discharge a liquid,
the first drive circuit, the second drive circuit, and the third drive circuit are located side by side in an order of the first drive circuit, the second drive circuit, and the third drive circuit on the substrate along one direction, and
the first through-hole is located between the first drive circuit and the second drive circuit in the one direction.
