    摘要： A laser image display device includes: a first laser light source capable of outputting a laser light having a first wavelength; a second laser light source capable of outputting a laser light having a second wavelength; and a color output conversion controller capable of individually controlling power of the first and the second laser light source displaying the pixels constituting an image according to an input signal. When an input signal is contained at the end point of the color reproducible region and the laser light having the first wavelength is driven substantially by a first maximum power while the laser light having the second wavelength is driven substantially by a second minimum power, the color output conversion controller displays in pixels, a color contained in the color reproducible region excluding the end point in the pixels by using the laser light of the first wavelength at a first power below the first maximum power and the laser light of the second wavelength at a second power above the second minimum power.
