摘要： An image displaying apparatus includes laser light sources corresponding to a plurality of colors, while at least one of the laser light sources corresponding to one of the colors includes a plurality of wavelength conversion laser light sources corresponding to a mutually same color and has a plurality of outputs. The image displaying apparatus is operable to display a color image by causing a spatial modulation element to perform a spatial modulation process on laser beams output from the laser light sources by using a field sequential method. When the spatial modulation element performs the spatial modulation process on the laser beams output from one of the laser light sources (e.g., the green laser light source) having a plurality of outputs, a drive controlling device causes green laser emitting units serving as the wavelength conversion laser light sources to sequentially output pulses so that the laser beams output from the green laser emitting units continuously form substantially constant laser outputs that have substantially the same peak power as each other.

摘要： In a projection type display apparatus includes an illumination device (including a light source), a light modulation element, a projection optical system that projects a modulated light from the light modulation element, and a screen onto which a projected light is projected. The projection optical system includes a refraction type optical system that refracts the modulated light from the light modulation element, and a hologram element disposed on a position remote from the screen and shifted in a direction parallel to the screen from a center of the screen. The hologram element projects the modulated light having passed through the refraction type optical system onto the screen so that a light ray of the center of the modulated light is inclined with respect to a normal line of the screen.
