Abstract
The invention provides a liquid crystal empty box and manufacturing method thereof, a liquid crystal lens using the liquid crystal box empty box. The liquid crystal empty box comprises a first substrate, a second substrate and a support body. The support body is used for maintaining a distance between the first substrate and the second substrate. The support body comprises a first support body made of photopolymerizable materials or photolysis materials. A second support body is located in the first support body, and is used for bracing the first support body. Because the outer layer of the support body is made of photopolymerizable materials and photolysis materials which have adhesive force, after the outer layer is fixed to the first substrate, the displacement is not prone to happen. The second support body located at the inner layer is used for exerting a support function to the photopolymerizable materials or photolysis materials to prevent the support body from deformation by external compression. Therefore, a strength requirement of a high size can be achieved with a very small particle size, the problem that in a big thick box device, it is needed to establish a large particulate size support body which causes the displayed appearance of light spots and black spots is solved.
