Display device

A display device, comprising:

• a light-transmitting portion arranged on an electromagnetic-wave-transmissive panel;
• a display light source arranged at an inner side of the light-transmitting portion, the display light source being configured to emit light to the light-transmitting portion to illuminate and display the light-transmitting portion;
• and
• a housing including an opening, the housing accommodating the display light source, the light-transmitting portion being arranged in the opening, wherein
• 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 reflecting visible light and transmitting infrared light,
• the first color exhibiting layer has a transmittance of 20% or more for light having a specific wavelength, and
• 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.
