Abstract
Provided are an illumination unit and a display capable of achieving size reduction in a case where a plurality types of light sources emitting light with various different wavelengths are in use. An optical-path conversion memberis provided for performing optical-path conversion to light (red laser light Lr, green laser light Lg, and blue laser light Lg) coming from three types of light sources (a red laserR, a green laserG, and a blue laserB) in a light source unitin such a manner that, compared with an angle formed by center rays in the light, an angle formed by center rays in outgoing light becomes much smaller. Such optical-path conversion is performed without using a large-scale optical system (optical members).
