Abstract
A liquid crystal phase modulation device includes a first substrate, a second substrate, a liquid crystal layer, and plural spacers. The second substrate is opposite to the first substrate. The first substrate has a first electrode layer, and the second substrate has a second electrode layer. The liquid crystal layer is between the first substrate and the second substrate. The spacers are between the first substrate and the second substrate.
