1. A display device displaying information to a user, the display device comprising:
a first sheet on which a pattern corresponding to the information is provided;
a light source configured to emit light to brighten the pattern; and
a light guide including (1) an incident surface provided at one end portion thereof with respect to a first direction perpendicular to the first sheet and permitting incidence of the light emitted from the light source and (2) an emission surface provided at the other end portion thereof with respect to the first direction and permitting emission of the light incident from the incident surface, wherein the light guide is configured to guide the light emitted from the light source to the first sheet so that the pattern is illuminated,
wherein, as viewed in the first direction, the incident surface is smaller than an area where the pattern is provided on the first sheet,
wherein, as viewed in the first direction, the emission surface includes (1) a first emission surface which overlaps at least a part of the pattern and has a portion overlapping the light source, and (2) a second emission surface which overlaps at least a part of the pattern and does not overlap the light source,
wherein the area where the pattern is provided is smaller than a combined area of the first emission surface and the second emission surface with respect to a plane orthogonal to the first direction, and
wherein the second emission surface is closer to the first sheet than the first emission surface.
