Abstract
A display device includes a light-transmitting portion, a display light source arranged at an inner side of the light-transmitting portion, and a housing including an opening. The housing accommodates the display light source and the light-transmitting portion is arranged in the opening. The light-transmitting portion includes a transparent plastic base member, a first color exhibiting layer containing dye or pigment, and a second color exhibiting layer containing a filler made of a cold mirror thin film. The first color exhibiting layer has a transmittance of 20% or more for light having a specific wavelength. The second color exhibiting layer has a reflectance of 80% or less for light having a wavelength not absorbed by the dye or the pigment of the first color exhibiting layer and a transmittance of 60% or more for light having a wavelength absorbed by the dye or the pigment of the first color exhibiting layer.
