An optical multilayer film includes first and second optical layers, and a refracting layer. The first optical layer has a light-exit surface. The second optical layer has a light-incoming surface facing the light-exit surface of the first optical layer, and a light-outgoing surface opposite to the light-incoming surface and formed with a light-converging structure. The refracting layer is disposed between and is in contact with the first and second optical layers, is made from a transparent material, and has a refractive index that is smaller than that of the second optical layer.

Optical multilayer film and a backlight module utilizing the same

A backlight module includes a light guide plate and a light source. The light guide plate includes a first end portion, a second end portion, a middle portion between the first and second end portions, a top face extending from the first end portion to the second end portion, a bottom face extending from the first end portion to the second end portion, a light entrance face interconnecting the top and bottom faces at the first end portion, and a plurality of prismatic strips formed on the bottom face. The prismatic strips have a lower density at the first end portion as compared to the middle portion. The density is defined as a total length of the prismatic strips per unit area of the bottom face. The light source is disposed adjacent to the light entrance face.
