Green light from solid-state light source 1G and red light from solid-state light source 1R are irradiated upon display element 5 by way of the same light path, green light from solid-state light source 2G and red light from solid-state light source 2R are irradiated upon display element 6 by way of the same light path, and blue light from solid-state light source 1B is irradiated upon display element 7. Control unit 10 lights solid-state light sources 1G and 1R in time division, causes an image based on first video signal S1 to be displayed on display element 5 during lighting of solid-state light source 1R, and causes an image based on second video signal S2 to be displayed on display element 5 during lighting of solid-state light source 1G. Control unit 10 further lights solid-state light sources 2G and 2R in time division, causes an image based on first video signal S1 to be displayed on display element 6 during lighting of solid-state light source 2R, and causes an image based on second video signal S2 to be displayed on display element 6 during lighting of solid-state light source 2G Control unit 10 further constantly lights solid-state light source 1B and causes an image based on third video signal S3 to be displayed on display element 7. |
