Abstract
A backlight module includes a light guide plate (), a light source (), a reflecting sheet (), a diffusion sheet (), and a reflective polarizing beam splitter (). The light guide plate includes a light input surface (), a light output surface () adjacent to the light input surface, a reflecting surface () opposite the light output surface, and a number of microstructures () located on the reflecting surface. In the light guide plate, stress-induced birefringence is introduced to achieve a polarization state conversion, thereby facilitating efficient use of the light generated by the light source.
