1. A liquid discharge apparatus comprising:
a print head that discharges a liquid; and
a substrate unit electrically coupled to the print head, wherein
the print head includes
a first discharge section that has a first piezoelectric element that is displaced by receiving a first driving signal and discharges a liquid by displacement of the first piezoelectric element, and
a first connector electrically coupled to the substrate unit,
the substrate unit includes
a second connector that is electrically coupled to the print head by being fitted to the first connector, and
a wiring substrate provided with a plurality of circuit components having the second connector,
the wiring substrate is a rigid flexible substrate including a plurality of rigid members provided with the plurality of circuit components and a flexible member more flexible than the plurality of rigid members,
the flexible member includes a first surface, a second surface opposite to the first surface, a first region, a second region, a third region, a fourth region, and a fifth region,
the fourth region is positioned between the first region and the second region,
the fifth region is positioned between the second region and the third region,
the plurality of rigid members include a first rigid member, a second rigid member, a third rigid member, and a fourth rigid member,
the first rigid member includes a first front surface, and is laminated on the first surface of the first region such that the first front surface extends along the first surface,
the second rigid member includes a second front surface, and is laminated on the first surface of the second region such that the second front surface extends along the first surface,
the third rigid member includes a third front surface, and is laminated on the first surface of the third region such that the third front surface extends along the first surface,
the fourth rigid member includes a fourth front surface, and is laminated on the second surface of the third region such that the fourth front surface extends along the second surface,
the first rigid member and the second rigid member are positioned such that the first front surface and the second front surface face each other when the flexible member is bent in the fourth region,
the third rigid member is positioned such that a normal direction of the third front surface intersects both a normal direction of the first front surface and a normal direction of the second front surface when the flexible member is bent in the fifth region,
the second connector is provided on the fourth rigid member, and
sizes of the third rigid member and the fourth rigid member when viewed along a direction from the third rigid member to the fourth rigid member are smaller than a size of the print head when viewed along a direction from the first connector to the first discharge section.
