Front light module and reflective display device

A front light module and reflective display device are disclosed. The front light module is covered on a reflective display and includes a front light plate, a plurality of dot structures and a first optically clear adhesive. The front light plate has a light exiting surface, a bottom surface and a light incident surface, the light exiting surface is opposite to the bottom surface, and the light exiting surface and the bottom surface are adjacent to the light incident surface. The dot structures are arranged on the bottom surface, wherein the angle between the bottom surface and the thickness of the side wall surface of each dot structures is 100~115 degrees. The depth of each dot structures is d, the width of each dot structures is w, and it conforms to the relational expression of d / w < 0.15. The first optically clear adhesive is coated on the bottom surface and is filled in the dot structures. Accordingly, through the aforementioned dot structures feature, the uneven light output caused by the bright ban
