A projector system includes a light source unit, a spatial light modulation device that controls light from the light source unit for each pixel to form an optical image, and a projection optical system that projects the optical image formed by the spatial light modulation device onto a target screen. The light source unit includes a solid-state light source and a wavelength conversion device. The solid-state light source emits first light, the first light including blue light with a peak wavelength in the range of 430 to 470 nm and green light with a peak wavelength in the range of 480 to 550 nm. The wavelength conversion device contains at least a red phosphor with a Ce luminescent center. The red phosphor emits second light upon receiving the green light. The second light has a spectrum with a peak wavelength in the range of 600 to 700 nm.
