Claims
- 1. A reflection-type liquid crystal displaying device comprising:
- at least one optically transmitting first substrate on which an optically transmitting electrode is formed;
- a second substrate that reflects light;
- a liquid crystal layer disposed between the first and the second substrates; and
- an anisotropic scattering film for anisotropically scattering an incident light,
- wherein the anisotropic scattering film is formed directly on a side of the first substrate,
- wherein the anisotropic scattering film is formed on a side of the first substrate, the side being adjacent to the liquid crystal layer.
- 2. The device of claim 1, wherein the anisotropic scattering film comprises a transparent film containing a transparent matrix material in which a transparent substance having a refractive index different from that of the transparent matrix material is dispersed so that the incident light can be anisotropically scattered.
- 3. The device of claim 2, wherein the transparent substance includes anisotropic shaped particles and the particles are homogeneously dispersed in an orderly manner in the transparent film containing the transparent matrix material so that the particles are arranged parallel to each other.
- 4. The device of claim 3, wherein the anisotropic shape of the particles is spheroid, a rectangular parallelepiped, or a circular cylinder.
- 5. The device of claim 4, wherein the difference between the refractive indices of the transparent matrix material and of the transparent substance is at least 0.0001.
- 6. The device of claim 2, wherein the transparent matrix material comprises a transparent resin.
- 7. The device of claim 1, wherein the second substrate includes a metallic reflecting film.
- 8. The device of claim 1, wherein the second substrate includes a dielectric mirror film.
- 9. A reflection-type liquid crystal displaying device comprising:
- at least one optically transmitting first substrate on which an optically transmitting electrode is formed;
- a second substrate that reflects light;
- a liquid crystal layer disposed between the first and the second substrates; and
- an anisotropic scattering film for anisotropically scattering an incident light,
- wherein the anisotropic scattering film is formed directly on a side of the first substrate,
- wherein the anisotropic scattering film is formed on a side of the first substrate, the side being that opposite to the liquid crystal layer.
- 10. The device of claim 9, wherein the anisotropic scattering film comprises a transparent film containing a transparent matrix material in which a transparent substance having a refractive index different from that of the transparent matrix material is dispersed so that the incident light can be anisotropically scattered.
- 11. The device of claim 10, wherein the transparent substance includes anisotropic shaped particles and the particles are homogeneously dispersed in an orderly manner in the transparent film containing the transparent matrix material so that the particles are arranged parallel to each other.
- 12. The device of claim 11, wherein the anisotropic shape of the particles is spheroid, a rectangular parallelepiped, or a circular cylinder.
- 13. The device of claim 12, wherein the difference between the refractive indices of the transparent matrix material and of the transparent substance is at least 0.0001.
- 14. The device of claim 10, wherein the transparent matrix material comprises a transparent resin.
- 15. The device of claim 9, wherein the second substrate includes a metallic reflecting film.
- 16. The device of claim 9, wherein the second substrate includes a dielectric mirror film.
