Abstract
The present disclosure provides a front light module, which includes a light source and a light guide plate. The light source includes a linear light strip which includes a plurality of light-emitting diode elements. The light guide plate and the light source are disposed on a same plane. The light guide plate has two opposite surfaces, wherein one of the two surfaces has a plurality of microstructures, and the other of the two surfaces is free of any microstructures. A distribution density of the microstructures and distances of the microstructures from the light source satisfy the following equation: y=Kx, wherein y is the distribution density of the microstructures, measured in units of number/square millimeter; x is a distance between a sampling centerline and a side of the light guide plate closer to the light source, measured in units millimeter; K is a constant; and n is 1.5-3.0.
