摘要： The present disclosure provides a liquid crystal grating and a driving method therefor, and a three-dimensional (3D) display device. The liquid crystal grating includes: a first substrate; a second substrate, where the second substrate and the first substrate are oppositely arranged; a liquid crystal layer, where the liquid crystal layer is located between the first substrate and the second substrate; and a first transparent grating electrode layer located at a side, facing the liquid crystal layer, of the first substrate; where the first transparent grating electrode layer includes a plurality of first strip-shaped electrodes extending in a first direction and arranged at intervals in a second direction, and each of at least part of the first strip-shaped electrodes is divided in the first direction into at least two first strip-shaped sub-electrodes arranged independently.
