A liquid crystal display device includes first and second substrates, gate and data lines formed on the first substrate and crossing each other to define a pixel region, a first common electrode in a first part of the pixel region, the first common electrode having a plate shape, a plurality of first pixel electrodes directly over the first common electrode and at a first fixed interval in the first part of the pixel region, a second pixel electrode alternately arranged with a second common electrode at a second fixed interval in a second part of the pixel region, and a layer of liquid crystal molecules between the first and second substrates.

The invention relates to a bistable composite film of polymer dispersed liquid crystals and a manufacturing method thereof. The composite film is composed of two pieces of flexible transparent conducting film and a layer of polymer dispersed liquid crystals, wherein, the two pieces of flexible transparent conducting film are etched with a coplanar conversion electrode; the layer of polymer dispersed liquid crystals is highly active polyurethane acrylic ester; the liquid crystals are nematic phase liquid crystal molecules with large birefringence. When imposing a coplanar horizontal electric field, the bistable composite film of the polymer dispersed liquid crystals is in closed and scattering state and still keeps the scattering state after the electric field is eliminated; when imposing a coplanar comb-shaped electrode short-circuit on an opposite electric field, the bistable composite film of the polymer dispersed liquid crystals is in open and transparent state and still keeps the transparent state after the electric field is eliminated. The bistable composite film of the polymer dispersed liquid crystals has the manufacturing method that: after being mixed, the highly active polymer and the nematic phase liquid crystals with the large birefringence are separated to form the structure that the polymer wraps crystal liquid droplets. The invention uses the simple design proposal and depends on changing the direction of the electric field to realize zero field stability of the polymer dispersed liquid crystals so as to further acquire an electronic-paper technology with better energy conservation; or the bistable composite film of polymer dispersed liquid crystals can be specially applied to the fields of building decoration and jewelry counters and so on as a dimming function film which is clipped in glass.

Disclosed is a patterned retarder film which comprises a substrate, a patterned configuration layer and a liquid crystal layer. The patterned configuration layer includes a plurality of first regions and a plurality of second regions A liquid crystal layer is disposed on the patterned configuration layer, wherein liquid crystal molecules above the first regions is arranged irregularly because of the protrusions, the liquid crystal molecules above the second regions are aligned with the aligning micro-structures. The liquid crystal layer in above the first regions provides a first phase retardation, the liquid crystal layer above the second regions provides a second phase retardation, and the difference between the first phase retardation and the second phase retardation is 180°. The method for manufacturing the same is disclosed.

The invention belongs to the technical field of optical film materials, and relates to a preparation method of a distorted grain boundary phase-A liquid crystal mixed material with a wide temperaturerange. The method comprises the following steps: mixing phase-A-cholest-N*phase transformed liquid crystal molecules, nematic phase micromolecular liquid crystals and nematic phase-smectic phase liquid crystal molecules to obtain a distorted grain boundary phase A, obtaining a wide-temperature-range distorted grain boundary phase A by controlling a mixing ratio of the molecules in the mixing process, thus obtaining the wide-temperature-range TGBA phase; and adding chiral additives into the proportioned TGBA phase to adjust an initial reflection wave site when the liquid crystal mixed materialis in the TGBA phase. The liquid crystal mixed material provided by the invention has wider TGBA phase temperature range, the initial (cooling process) reflection wave site when the liquid crystal mixed material is in TGBA phase can be adjusted at the same time, and the experimental process is simple and easy to operate.
