Abstract
A liquid crystal grating and its fabrication method, and a display panel are provided in the present disclosure. The liquid crystal grating includes a first light adjustment component and a second light adjustment component, disposed oppositely. The first light adjustment component includes a first liquid crystal panel and a first polarization adjustment component; the second light adjustment component includes a second liquid crystal panel and a second polarization adjustment component; and using a second direction as an extending direction of a rotation axis, when the first light adjustment component is rotated 180° around the rotation axis, an alignment direction of the first liquid crystal panel is in parallel with an alignment direction of the second liquid crystal panel, and an optical axis direction of the first polarization adjustment component is in parallel with an optical axis direction of the second polarization adjustment component.
