1. A liquid crystal device comprising:
a first substrate;
a second substrate including a first protruding portion that protrudes from the first substrate along a first direction, the first protruding portion including a first coupling portion;
a liquid crystal layer disposed between the first substrate and the second substrate;
a first flexible substrate electrically coupled to the first coupling portion, the first flexible substrate extending along the first direction;
a third substrate bonded to the first substrate, the third substrate including:
a body portion that overlaps with the first substrate and includes a heating member that is disposed outside a display region and that is not disposed in the display region, the heating member including:
a first portion that extends along a second direction intersecting the first direction,
a second portion that extends from the first portion along a third direction opposite the first direction and intersecting the second direction,
a third portion that extends from the second portion along a fourth direction opposite the second direction and intersecting the third direction,
a fourth portion that extends from the third portion along the first direction, and
a fifth portion that extends from the fourth portion along the second direction, the fifth portion being disposed apart from the first portion; and
a second protruding portion that protrudes from the body portion along the first direction and that protrudes from the first substrate along the first direction, the second protruding portion including:
a first extending portion that extends from the first portion along the first direction,
a second coupling portion that is electrically coupled to the first extending portion,
a second extending portion that extends from the fifth portion along the first direction, and
a third coupling portion that is electrically coupled to the second extending portion;
a second flexible substrate electrically coupled to the heating member via the second coupling portion, the second flexible substrate extending along the first direction; and
a third flexible substrate that is electrically coupled to the heating member via the third coupling portion, the third flexible substrate extending along the first direction.
