Abstract
Disclosed are a light guide device, an optical display system, and a display device. The light guide device includes a substrate and a first diffraction structure provided at the substrate. The first diffraction structure includes a first grating. The first grating includes a plurality of first grating units provided at intervals of a first period Palong a first vector direction uand at intervals of a second period Palong a second vector direction u. The first vector direction uis intersected with the second vector direction u, the first period Pis longer than the second period P, forming unequal periods in two vector directions, and the first period Pis at least 1.5 times the second period P
