A light transmissive substrate is provided and has a first surface and a second surface opposite to the first surface. Then, a plurality of first rod-shaped lenses are formed on the first surface. The rod-shaped lenses extend along a first direction and are arranged along a second direction. After that, a plurality of second stripe-shaped prisms are formed on the second surface. The stripe-shaped prisms extend along the second direction and are arranged along the first direction. Next, an electromagnetic wave beam is made to pass through the rod-shaped lenses, the light transmissive substrate and the stripe-shaped prisms in sequence. A first portion of each of the stripe-shaped prisms exposes and leaves a second portion of each of the stripe-shaped prisms unexposed. Then, the second portions of the stripe-shaped prisms are removed.

    摘要: A light guide plate capable of guiding a light beam from a light emitting device and a backlight module using the light guide plate are provided. The light guide plate includes a light-transmissive substrate and optical structures. The light-transmissive substrate has a first surface, an opposite second surface, and an incident surface connecting the first and the second surface. The light beam enters the light-transmissive substrate through the incident surface and is emitted out of the light-transmissive substrate through the first surface. The optical structures are disposed on the second surface. Each optical structure has a first total internal reflection (TIR) surface, a second TIR surface, and a third TIR surface. The second TIR surface connects the first and third TIR surfaces. Part of the light beam from the incident surface is totally internally reflected by any adjacent two of the first, second, and third TIR surfaces in sequence.
