Abstract
To improve the brightness of irradiated light in the lighting apparatus using a liquid crystal element. Alighting apparatus includes: a light source; a condensing unit that condenses light emitted from the light source so that it forms a focal point at a predetermined position; a liquid crystal element arranged corresponding to the position of the focal point; a first polarizing element located on a light incident side of the liquid crystal element; a second polarizing element located on a light emitting side of the liquid crystal element; a first prism array that refracts a traveling direction of the light heading toward the liquid crystal element and a second prism array that refracts a traveling direction of light emitted from the liquid crystal element.
