Abstract

A light guide plate cooperating with at least two LEDs includes at least an incident surface for receiving incident light, a bottom surface for reflecting and diffusing the incident light, a light emitting surface for directing the light to emit, wherein, a plurality of prisms which are perpendicular with the incident surface are formed on the light emitting surface. The distance of any two contiguous prisms is constant and the width of prisms is inconstant. The prisms are distributed like this: between any two contiguous LEDs, the prisms' width reduce from the two LEDs' inside edges to the space center. In any other part, the prisms' width equal to the distance of any two contiguous prisms.
