摘要： The present invention provides a light guide plate and a backlight module containing the light guide plate. The light guide plate includes a plate body and a metal layer formed on the plate body. The plate body includes a bottom face, a top face opposite to the bottom face, and a plurality of side faces between the bottom face and the top face. The metal layer is formed on at least one side edge of the top face. The metal layer shows reflectivity of which difference is less than 20% for lights having wavelength between 380-780 nm. The light guide plate uses the metal layer formed on the top face to reflect light back into the light guide plate to confine the light within the light guide plate so as to prevent light leakage and ensure light intensity and homogeneity of the light guide plate.

摘要： A light guide plate includes upper microstructures forming an upper surface. The upper microstructures are distributed in a successive convex-concave alternating arrangement in a direction perpendicular to propagation direction of light in the light guide plate. The light guide plate is divided according to the distance from the light source in the light propagation direction into a proximal side and a remote side. With H indicating height of shape features of the upper microstructures and P indicating spacing between the shape features of the upper microstructures, the shape features of the upper microstructures show a distribution that is variable in the light propagation direction in such a way that the variation satisfies the condition that aspect ratio H/P of the upper microstructures at the proximal side of the light guide plate is less than aspect ratio H/P of the upper microstructures at the remote side of the light guide plate.
