Abstract
A head-up display includes an image generating unit and a waveguide glass. The waveguide glass faces toward the image generating unit. The waveguide glass includes a first microstructure, a second microstructure and a third microstructure. The first microstructure has a first width. The second microstructure is adjacent to the first microstructure. The third microstructure is adjacent to the second microstructure. The third microstructure has tiling areas adjacent to each other. A gap between the two adjacent tiling areas is less than half of the first width.
