Abstract:
A light guide plate (20) has a light incidence surface (221) for receiving light, a light emitting surface (223) for emitting light, and a bottom surface (222). The light emitting surface has a plurality of diffraction grating units. Each diffraction grating unit has a strong diffractive portion and a weak diffractive portion. In each diffraction grating unit, grating directions of the strong and weak diffractive portions are orthogonal to each other. Area ratios of the strong diffractive portions in the diffraction grating units progressively increase with increasing distance away from the light incidence surface. The grating directions of the strong diffractive portions may vary according to the locations of the diffraction grating units relative to a light source. These features improve the overall efficiency of utilization of light, and enable the light emitting surface to output highly uniform light.
