Abstract
A light source module and a display device are provided. The light source module includes a light source, a light guide plate, and an optical film set including multiple first optical microstructures having a first surface, multiple second optical microstructures having a second surface, and multiple third optical microstructures having a third surface. Each of the multiple first optical microstructures has a first vertex angle, each of the multiple second optical microstructures has a second vertex angle, and each of the multiple third optical microstructures has a third vertex angle. The third vertex angle is less than the first vertex angle, and the first vertex angle is less than or equal to the second vertex angle. By configuring the aforementioned optical microstructures, the light source module of the disclosure may greatly improve the collimation of light and has favorable luminance.
