Abstract
The invention provides a light guide plate and a back light module using the same. The light guide plate is formed by the connection of multiple sub-light guide plates by hinge structures, wherein the contact surface of each sub-light guide plate is designed into a concave-convex matching cambered surface structure to enable the whole light guide plate to be bent to a certain extent along the cambered surfaces. Therefore, the light guide plate and the back light module have the advantage of large bending amplitude and are not influenced by the dimension.
