摘要： A light diffusion element includes a light diffusion layer that contains at least two types of liquid crystal molecules each having a different light scattering characteristic defined by a voltage and a refractive index. A pair of electrodes sandwiches the light diffusion layer, an applying unit generates and applies a variable voltage to the pair of electrodes, and a voltage changing unit varies the voltage generated by the applying unit. The voltage changing unit varies the voltage such that each of the refractive indexes of the liquid crystal molecules in the light diffusion layer changes temporally.

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.
