1. A front light module, comprising:
- a plurality of stacked transparent materials, comprising;
a first surface;
a second surface, opposite to the first surface; and
a light incident surface; and
a plurality of light sources, configured to provide a plurality of light beams and disposed beside the light incident surface, wherein an edge portion is at a location of at least one of the transparent materials that is adjacent to the light sources, one of the transparent materials has the light incident surface, the edge portion comprises a plurality of first sub-edges and a plurality of second sub-edges, the light sources are disposed in alignment with the first sub-edges, and the first sub-edges and the second sub-edges are alternately arranged in a row, wherein a buffer portion of the one of the transparent materials having the light incident surface is exposed to an outside of the front light module by the edge portion, one of distances from the first sub-edges to the light incident surface is defined as a first distance,one of distances from the second sub-edges to the light incident surface is defined as a second distance,the first distance is larger than the second distance, the first distance and the second distance are larger than zero, and the buffer portion has the first distance and the second distance.

Abstract
A front light module including a plurality of stacked transparent materials and a plurality of light sources is provided. The light sources are configured to provide light beams, and are disposed beside the light incident surface of the transparent materials. An edge portion is at a location of at least one of these transparent materials which is adjacent to the light sources. The edge portion includes a plurality of first sub-edges and a plurality of second sub-edges. The first sub-edges are disposed corresponding to the light sources. The first sub-edges and the second sub-edges are arranged alternately in a row, and one of the distances from the first sub-edges to the light entering surface is greater than one of the distances from the second sub-edges to the light entering surface. Furthermore, a display module is also provided.
