Abstract:
This display device comprises: a light source that emits light; a design layer that is disposed to face the light source and has a design on at least a surface on the reverse side from the light source; a light passage region that is disposed in the design layer at a position corresponding to the light source, allows the light emitted from the light source to pass therethrough, and cannot be viewed at a viewing distance; and a light emission luminance control unit that performs control such that the light emission luminance of the light emitted from the light source and having passed through the light passage region becomes higher than or equal to a value obtained by multiplying the average design layer luminance of the design layer by an allowable limit value at which the design disappears.
