PURPOSE: A polarized light projecting apparatus is provided to minimize the inconsistency of polarizing axis in a light projecting area. CONSTITUTION: A polarized light projecting apparatus comprises a linear shape light source(1) which project diffusion light, a reflection mirror(2), and a grid polarizing element(10) which polarizes light from the reflection mirror and the light source. The cross section of the reflection mirror is parabolic shape. The central point of the light source is placed on the grid polarizing element side. |
