Abstract
A backlight module includes a light guide panel, and first and second light sources. The light guide panel has a light-emitting surface and a bottom surface opposite to each other. Two adjacent sides of the bottom surface are respectively connected to a first light-incident surface, and a second light-incident surface. The first and second light sources are disposed adjacent to the first and second light-incident surfaces, respectively. Light-guiding patterns are arranged on the bottom surface or the light-emitting surface. Any adjacent two of the light-guiding patterns have a first pitch in a first direction and a second pitch in a second direction, respectively. The first pitch is decreased gradually from a position near the first light-incident surface toward a position far from the first light-incident surface. The second pitch is decreased gradually from a position near the second light-incident surface toward a position far from the second light-incident surface.
