Claim 0:
1. A liquid crystal phase shifter, comprising: a first substrate and a second substrate opposite to each other, and a liquid crystal layer between the first substrate and the second substrate, wherein,
the first substrate comprises a first base plate and a first electrode on the first base plate;
the first electrode comprises a main body structure on a side of the first base plate distal to the liquid crystal layer and at least one branch structure on a side of the first base plate proximal to the liquid crystal layer, the at least one branch structure is connected to the main body structure through at least one through hole penetrating through the first base plate, respectively, and is spaced apart from each other in a lengthwise direction of the main body structure; and
the second substrate comprises a second base plate and a second electrode on the second base plate, and an orthographic projection of the second electrode on the first base plate at least partially overlaps an orthographic projection of the at least one branch structure on the first base plate.
