Provided is a molded product which exhibits an excellent jet black color in a case where a light source is turned off, can exhibit a specific color tone in a case where the light source is turned on, and has a high solar transmittance. The molded product of the present invention is a molded product comprising a transparent resin, in which an L* value of reflected light is 35 or less, in a wavelength range of 430 nm or more and 700 nm or less, a wavelength at which a maximum value of a light transmittance is shown is in a wavelength range of 430 nm or more and less than 680 nm, and a light transmittance at a wavelength of 770 nm is 0.5% or more.

Molded product and display device

An indicator lamp of the present invention includes a lamp body, a light source unit disposed inside the lamp body, and a light transmissive resin member disposed at a position for transmitting light that is emitted from the light source unit and for outputting the light from the lamp body. The light source unit emits red light having a maximum value of light intensity at a wavelength of 600 nm or longer and 700 nm or shorter. The light transmissive resin member has an L* value of 35 or less, a transmittance of light having a wavelength of 675 nm of 90% or greater and a total light transmittance of 5% or greater in the state in which an optical path length of transmitting light is 2 mm. This configuration provides an indicator lamp with excellent design that shows its presence by showing a red chromatic tone when a light source is turned on and that shows a black color tone when the light source is turned off.
