The present disclosure provides a liquid crystal phase shifter, comprising a first substrate and a second substrate which are oppositely arranged, and a liquid crystal layer positioned between the first substrate and the second substrate, wherein a plurality of spacers are distributed in the liquid crystal layer, the spacers are in contact with the first substrate and the second substrate, and include a first spacer arranged on the first substrate and a second spacer arranged on the second substrate, and the first spacer and the second spacer are abutted. The present disclosure also provides a manufacturing method of the liquid crystal phase shifter. The first spacer and the second spacer are arranged on the first substrate and the second substrate respectively, so that the thickness of a support of the liquid crystal phase shifter being 100 µm or above is realized, and the performance of the liquid crystal phase shifter is ensured. Besides, the liquid crystal phase shifter is easy to manufacture, and the liquid crystal phase shifter with the thick cell can be manufactured on a large scale.
