Abstract
Provided are a liquid crystal grating and a stereoscopic display device. A liquid crystal grating includes a first substrate, a second substrate and a liquid crystal layer, where the liquid crystal layer is located between the first substrate and the second substrate. The liquid crystal grating includes multiple grating units which are arranged along a first direction, where a grating unit includes multiple first electrodes and multiple second electrodes; the multiple first electrodes are located between the first substrate and the liquid crystal layer and are disposed at intervals from each other along the first direction; the multiple second electrodes are located between the second substrate and the liquid crystal layer and are disposed at intervals from each other along the first direction. At least two first electrodes have different voltages, and at least two second electrodes have different voltages.
