    摘要: Provided is a liquid crystal illumination device capable of providing a high-efficiency and high-intensity liquid crystal panel. The liquid crystal illumination device includes a liquid crystal panel, a light source configured to project light to the liquid crystal panel, a first diffusion unit configured to diffuse light projected from the light source, a first light guide unit configured to include a reflection surface formed in such a way as to radially widen from the light source side toward the liquid crystal panel side, reflect light diffused by the first diffusion unit at the reflection surface, and guide the light, a reflecting mirror on which an opening is formed, part of the light guided by the first light guide unit being reflected and returned to inside the first light guide unit, and remaining light passing through the opening, a light collecting unit configured to collect light passing through an opening on the reflecting mirror, and a second diffusion unit configured to diffuse light collected by the light collecting unit toward the liquid crystal panel. An opening on the reflecting mirror is formed correspondingly to a display region where the liquid crystal panel display an image. A haze value of the first diffusion unit is set to a value higher than a haze value of the second diffusion unit.
