Abstract
A back light module comprising a light-emitting module, a light transparent refraction plate and a light guide plate is disclosed. The light-emitting module comprises a substrate and several light-emitting components disposed on the substrate. Each light-emitting component has a light-emitting surface. The light transparent refraction plate is disposed on the substrate and has several apertures. Each aperture exposes a corresponding light-emitting surface, and has a sidewall higher than the light-emitting surface. The light guide plate has a lateral light incident surface facing the light-emitting surface and pressing the light transparent refraction plate. The refractive index of the light transparent refraction plate is larger than that of the light guide plate, such that the light emitted by each light-emitting component will enter the light guide plate after passing through the light transparent refraction plate.
