A planar-light apparatus with a non-straight direction light module is provided. The planar-light apparatus mainly comprises a light-guiding plate and a light module. The light-guiding plate comprises a light-incident surface and a light-output surface perpendicular to the light-incident surface, and a scattering surface opposite to the light-output surface. Further, the light module connected to the light-guiding plate is used for emitting a light onto the light-incident surface, and the light module is opposite to the light-incident surface of the light-guiding plate with a certain angle of incidence. The light is incident from the light-incident surface onto the light-guiding plate with a certain angle of incidence. Therefore, the first time the light is reflected, the inclination angle of the normal of the scattering surface is reduced, so that the number of the light reflections in the light-guiding plate is also reduced. Since the light is output from the light-output surface after fewer times of reflection, the light utilization efficiency is improved.
