Abstract
A display device includes a sheet on which a pattern is printed, a light source emitting light to brighten the pattern; and a light guide guiding the light emitted from the light source to the sheet. The light guide includes an incident surface provided at one end portion thereof in a longitudinal direction and an emission surface provided at the other end portion thereof. As viewed in the longitudinal direction, the incident surface is smaller than an area where the pattern is printed in the sheet, the emission surface includes a first emission surface which overlaps at least a part of the pattern and has a portion overlapping the light source, and a second emission surface which overlaps at least a part of the pattern and does not overlap the light source. The second emission surface is closer to the sheet than the first emission surface.
