Abstract
A display device includes a first image generating unit and a first waveguide glass. The first image generating unit is configured to emit first light. The first waveguide glass faces toward the first image generating unit. The first waveguide glass includes a first microstructure, two second microstructures and a third microstructure. The first microstructure is located between two ends at the same side of the two second microstructures. The third microstructure is located between the two second microstructures. The third microstructure has a first grating and a second grating. An extending direction of the first grating is different from an extending direction of the second grating. The second microstructure is configured to receive the first light of the first image generating unit transmitted through the first microstructure and transmit the first light to the third microstructure.
