Abstract
A direct-type light source module including N-stage light sources and an optical sheet is provided. The optical sheet is disposed above the N-stage light sources, and an optical distance between the i-th-stage light source and the optical sheet is smaller than an optical distance between the i+1-th-stage light source and the optical sheet, where 1≤i<N, and N is a positive integer greater than 1. A display device is also provided.
