Projection television with a wavelength-selection-type rear projection screen

A projection television having a rear projection screen including a Fresnel lens sheet and a lenticular lens sheet, wherein a dye or a pigment is mixed into the lenticular lens sheet which thereby has a waveform selection transmittance, wherein the transmittance of the rear projection screen is equal to or more than 65% when the wavelength of the incident light is less than 490 nm, wherein the transmittance of the rear projection screen is equal to or less than 60% when the wavelength of the incident light is within a range from 490 nm to 660 nm, and wherein the transmittance of the rear projection screen corresponding to the incident light, the wavelength of which is within a range from 490 nm to 580 nm, is larger than the transmittance corresponding to the incident light, the wavelength of which is within a range from 580 nm to 660 nm.
