摘要:
The invention has an object to provide a liquid crystal composite capable of sufficiently reducing the scattering of light in a focal conic state, a liquid crystal display element excellent in improvements of a color balance and a contrast, and electronic paper using the same. The content of a chiral material is higher in a cholesteric liquid crystal LCg for G than in a cholesteric liquid crystal LCb for B, and is higher in a cholesteric liquid crystal LCr for R than in the cholesteric liquid crystal LCg for G. The cholesteric liquid crystal LCr for R is prepared by mixing about 5 wt % of a chiral material CHl1 of an L-form with a base liquid crystal of an R-form, which contains 27 wt % of CHr1 of the R-form exhibiting a liquid crystallizability for a nematic liquid crystal LCn, and 3 wt % of a chiral material CHr2 of the R-form exhibiting no crystallizability.

A high-contrast reflective liquid crystal display device of a lamination type in which scattering in the focal conic state of cholesteric liquid crystal has been reduced is described. The reflective liquid crystal display device has two or more laminated liquid crystal panels respectively having a liquid crystal layer of the cholesteric liquid crystal having different selective reflection wavelengths and the liquid crystal panel having a liquid crystal layer into which the liquid crystal having a longer selective reflection wavelength has been implanted has a smaller orientation regulating force of the liquid crystal layer applied to the panel.

摘要:
A panel is formed by laminating a pair of substrates with each other. A first seal material is provided on one of the substrates and a second seal material is provided to completely surround the first seal material. The pair of substrates is laminated with each other in a state where a cell space is formed therebetween and the first and second seal materials are sandwiched between the substrates. An inner space of the second seal material containing the cell space is depressurized through an opening provided outside the first seal material and inside the second seal material. A portion where the second seal material is provided is removed so that the cell space formed by the first seal material remains.

A method of filling a multilayered cell with media. In the method, a multilayered cell having at least two layers, i.e., a first and second layer, is filled with media. The method comprises forming in the first layer a first medium injection region for filling the first layer with a first medium, forming in the second layer a second medium injection region for filling the second layer with a second medium, the second medium injection region corresponding to a region different from the first medium injection region, superposing the first and second layers, forming within the first medium injection region a first through-hole extending through the multilayered cell in the layer-thickness direction, forming within the second medium injection region a second through-hole extending through the multilayered cell in the layer-thickness direction, and injecting the first and second media into the first and second through-holes, respectively, to fill the first and second layers with the first and second media. Thus, a multilayered cell can be easily produced in a shorter time while attaining a reduction in deterioration during production.
