FRONT LIGHT UNIT AND FLAT DISPLAY APPARATUS EMPLOYING THE SAME

摘要

A front light unit of a flat display panel is provided to improve the contrast ratio by locating front polarizer at a front side of a light guide plate, thereby reducing noise light which is generated at the front surface from the light guided plate or display panel. A front light unit comprises a light source(110), a light guide plate(130), a polarizer(150), and a reflection prevention layer. The light guide plate has the front side guiding the light coming out in the optical source section, and faces to the rear side in which the guided light comes out and faces to the rear side. The front surface polarizer has the polarized light device which is arranged to be faced in the front side of the light guide plate and passes through only the light of the task polarization direction. The reflection prevention layer is formed on exterior in which the external light of the polarized light device is incident.
