1. An antenna device with an active area, comprising:
a first substrate;
a second substrate facing and spaced with the first substrate in a distance;
a plurality of working elements disposed between the first substrate and the second substrate and disposed in the active area;
a first partition element disposed between the first substrate and the second substrate, wherein the first partition element surrounds the active area;
a modulation material filled in the active area;
at least one buffer element connected with the active area, wherein the at least one of buffer element has a second partition element to provide a space for adjusting the amount of the modulation material in the active area;
at least one first spacer disposed in the at least one buffer element and
a first boundary layer and a second boundary layer, wherein the first boundary layer with a first material is disposed on at least one of the first substrate and the second substrate and disposed corresponding to the active area, the second boundary layer with a second material is disposed on at least one of the first substrate and the second substrate and disposed corresponding to the at least one buffer element, and an adhesive force between the modulation material and the first boundary layer is greater than an adhesive force between the modulation material and the second boundary layer.
