The invention discloses a package structure of a liquid lens which includes a first substrate and an electrode on the first substrate. The package structure includes a second substrate, a first sleeve, a second sleeve, a first circular member, and a second circular member. The first substrate is fixed at the first sleeve to form a holding chamber for receiving a first dielectric liquid and a second dielectric liquid. The second substrate is disposed on the liquid lens and fixed at the second sleeve. The first sleeve is fixedly connected inside the first sleeve and the second substrate. The second circular member is disposed on the first circular member. The first and second circular member are located and urged between the first sleeve and the second sleeve to form a reserved expansion chamber. |
