Abstract
A coating composition, a method for manufacturing a substrate using the same, and an optical device are provided. The method for manufacturing the substrate provides the substrate having excellent performance, as the substrate has fixed spacers on its surface by using a single layer in which nanoparticles and spacers are dispersed in an alignment film to reduce processes and cost. The optical device may be manufactured by such method.
Claims13
An optical device, comprising:
- a first substrate;
- a second substrate disposed opposite to the first substrate;
- a light modulation material existing between the first substrate and the second substrate;
- a first alignment film formed on one surface of the first substrate;
- and
- second alignment film formed on one surface of the second substrate,
- wherein the first alignment film is formed from a coating composition which comprises a substance for forming an alignment film, spacers, and nanoparticles,
- wherein the second alignment film is formed from a coating composition which comprises a substance for forming alignment film but does not comprise spacers and nanoparticles,
- wherein a density of the spacers is smaller than a density of the nanoparticles and
- the density of the nanoparticles is in a range of 1.5 g/cm3 to 10 g/cm3.
