1. An information display device, comprising:
a substrate portion;
a light emitter that is disposed on the substrate portion and is configured to emit light;
a housing that is disposed so as to cover the substrate portion;
a display sheet that is attached to the housing, has a display surface on which various kinds of information are displayed by light emitted from the light emitter, and whose display surface is deformable; and
a light guide region, which is a space formed by an inner wall surface of the housing and the display sheet, and guides the light emitted from the light emitter to the display sheet,
wherein the housing has a deformable portion that is provided to at least a portion in contact with the display sheet, and that is more readily deformable than the substrate portion in a direction intersecting a surface of the display sheet, and
the housing and the display sheet deform along a wall surface with which the display sheet comes into contact, and
a distance from the substrate portion to the display sheet in a direction intersecting the surface of the display sheet is greater than a distance from the substrate portion to an end of the light emitter.
