Claim:
1. A liquid crystal grating substrate, comprising a driving area used for forming a grating, wherein the liquid crystal grating substrate is provided with a first electrode structure, the first electrode structure comprises a plurality of electrode strips, and each electrode strip of the plurality of electrode strips comprises: a plurality of connecting parts arranged outside one side of the driving area, a projection part penetrating through the driving area arranged between every two adjacent connecting parts, and each projection part is provided with two mutually parallel driving parts arranged in the driving area; each of the two mutually parallel driving parts of all the projection parts are mutually parallel; and one end of each of the two mutually parallel driving parts in each projection part is connected with one end of a connecting part adjacent thereto; wherein one end of each electrode strip of the plurality of electrode strips is a connecting end, the connecting end is used for connecting a driving circuit, and the driving circuit is used for providing a driving voltage for the plurality of electrode strips; and the projection parts of the plurality of electrode strips have a same projection direction, and the projection parts of the plurality of electrode strips are arranged towards the projection direction of the projection parts according to a sequence such that distances between the two mutually parallel driving parts of the projection parts increase sequentially, and the projection part of one electrode strip of two adjacent electrode strips is arranged inside of the projection part of the other electrode strip of the two adjacent electrode strips.
