Abstract: A resin composition having electromagnetic wave transparency includes a base resin and filler particles added to the base resin. The filler particles have a higher relative permittivity than the base resin or have conductivity. The filler particles are unevenly distributed in the resin composition.

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.

Abstract: An exterior structure includes a non-light-transmitting portion configured to not transmit an external light, and a light-transmitting portion arranged near the non-light-transmitting portion and configured to reflect and transmit the external light. Light released outward from the non-light-transmitting portion includes light reflected by the non-light-transmitting portion. Light released outward from the light-transmitting portion includes a combination of light reflected by the light-transmitting portion and light applied to the light-transmitting portion from an inner side and passing through the light-transmitting portion. The color difference ΔE between the light released outward from the non-light-transmitting portion and the light released outward from the light-transmitting portion is 5 or less.
