Abstract:
A liquid crystal display apparatus according to an embodiment of the invention includes: a liquid crystal cell; polarizing plates placed on both sides of the liquid crystal cell; a light diffusing element provided outside of the polarizing plate on a viewer side; and a backlight unit provided outside of the polarizing plate on an opposite side of the viewer side. The backlight unit includes a collimated light source device that emits collimated light having a brightness half-value angle of 3° to 35° toward the liquid crystal cell, and a ratio Fw(BL)/Fw(FD) between a diffused light half-value angle Fw(FD) of the light diffusing element and the brightness half-value angle Fw(BL) of the collimated light is 0.5 or less.
