Abstract
A display device includes a light source and a front light plate. The light source is configured to emit light. The front light plate faces toward the light source. The front light plate is configured to receive the light. The front light plate includes a first microstructure and a second microstructure. The first microstructure is located on a first surface of the front light plate. The first microstructure has a first width. A conic constant of the first microstructure is in a range from −0.95 to 10. The second microstructure is adjacent to the first microstructure. The second microstructure has a second width. The first width of the first microstructure is greater than the second width of the second microstructure.
