Abstract
An illuminator and a display capable of achieving miniaturization are provided with use of a plurality of light sources emitting light with two or more kinds of wavelengths. In the light source unit, a red-color laserR, a green-color laserG, a blue-color laserB, a microlens section, and a microprismare integrated on a base material. Each laser beam emitted from each of the laser light sources is transmitted through the microlens section, and then, comes into the microprism. In the microprism, optical path conversion is performed to shorten the distance between the optical paths of the incident light beams (to allow the optical axes of the incident light beams to be closer to each other). Due to the above-described integration, the optical paths of the laser beams are allowed to be synthesized using the microscopic-scaled microlens section and microprisms.
