Liquid crystal display device |
| abstract |
(57) Abstract: A two-layer type liquid crystal display element in which two liquid crystal panels each having a chiral nematic liquid crystal obtained by adding an optically active substance to a nematic liquid crystal is stacked to obtain excellent black and white display. SOLUTION: In a two-layer type liquid crystal display element 1 in which two liquid crystal panels 10 and 20 each having a chiral nematic liquid crystal obtained by adding an optically active substance to a nematic liquid crystal, a center of a selective reflection wavelength in a planar state. The wavelength is 560 to 630 nm on the upper liquid crystal panel 10 side and 440 to 480 nm on the lower liquid crystal panel 20 side, and the refractive index anisotropy Δn of the nematic liquid crystal is 0.18 to The condition is 0.30. |
