Abstract
The present invention discloses a transparent liquid crystal display device and manufacturing method thereof. By adding dichroic dyes and the dichroic dyes having characteristic of rotating with liquid crystal materials, light absorption ability of polymer network liquid crystals is increased. The present invention is capable of solving a problem which a dark state is not sufficiently dark, thus enhances contrast performance of the transparent liquid crystal display device.

A method for manufacturing a transparent liquid crystal display device, the method comprising the steps of:
- providing a pair of substrates;
- adding dichroic dyes into liquid crystal materials, forming a dichroic dye-liquid crystal mixture;
- adding the dichroic dye-liquid crystal mixture into polymer monomers, forming a dichroic dye-liquid crystal polymer mixture;
- filling the dichroic dye-liquid crystal polymer mixture between the substrates;
- and
- irradiating the dichroic dye-liquid crystal polymer mixture by an ultraviolet light, forming a polymer network liquid crystal layer containing the dichroic dyes.
A transparent liquid crystal display device, comprising:
- a first substrate having a first transparent electrode;
- a second substrate having a second transparent electrode;
- and
- a polymer network liquid crystal layer between the first substrate and the second substrate, wherein the polymer network liquid crystal layer contacts the first transparent electrode and the second transparent electrode, and the polymer network liquid crystal layer is made of dichroic dyes, liquid crystal materials, and polymers.
