Abstract
A back light module having a light-guiding plate and a linear light source is provided. The light-guiding plate includes a light-guiding body with a light incident surface formed thereon and an optical-path-adjusting groove disposed on the light incident surface of the light-guiding body. The linear light source is disposed beside the light incident surface. The linear light source is suitable for providing light beams to the light incident surface. Furthermore, the optical path of the light beam is adjusted by the optical-path-adjusting groove before the light entering through the light incident surface into the light-guiding body. As a result, the back light module provides illumination with a higher degree of uniformity.
