| titleOfInvention | Cholesteric liquid crystal display |
| abstract | (57) [Summary] [PROBLEMS] To reduce the reflectance at the time of dark display or at the time of black display sufficiently, and to greatly improve the contrast. SOLUTION: Two layers of antireflection films 51, 53 and 52, 54 are formed between a substrate 11 and a transparent electrode 21 and between a substrate 12 and a transparent electrode 22, respectively. The optical thicknesses of the antireflection films 53 and 54 are respectively λ / 2, and the optical thicknesses of the antireflection films 53 and 54 are λ / 2. λ is an anti-reflection wavelength, which is set to, for example, 555 nm, which has the highest visibility. Accordingly, when the cholesteric liquid crystal 30 is in the focal conic orientation, the forward scattering of the incident light on the cholesteric liquid crystal 30 due to the reflection on the transparent electrode 22 is reduced around λ, and the reflectivity during dark display is reduced around λ. And the contrast is improved. Antireflection films may be formed on both sides of the transparent electrodes 21 and 22 so as to sandwich the transparent electrodes 21 and 22 respectively. The optical thickness of the transparent electrodes 21 and 22 may be set to λ / 2 without forming an anti-reflection film separately from the transparent electrodes 21 and 22. |
