Abstract
A liquid crystal phase shifter is provided, and includes a first substrate and a second substrate opposite to each other, and a liquid crystal layer between the first substrate and the second substrate. The first substrate includes a first base plate and a first electrode layer at a side of the first base plate proximal to the liquid crystal layer. The second substrate includes a second base plate and a second electrode layer at a side of the second base plate proximal to the liquid crystal layer. The first electrode layer includes a main body structure having a first side and a second side opposite to each other with respect to a length direction of the main body structure, and a plurality of branch structures connected to at least one of the first side and the second side of the main body structure.
