Light controlling apparatus and method of fabricating the same

A method of fabricating a light controlling apparatus, comprising:

• laminating a first electrode unit to a second electrode unit, where the first and second electrode units have a refractive index in a range of 1.6 to 1.8;
• forming a mixed liquid crystal unit having a refractive index in a range of 1.3 to 1.6 between the first electrode unit and the second electrode unit, the mixed liquid crystal unit having a mixed liquid crystal, and the mixed liquid crystal having a first monomer, a second monomer and a liquid crystal;
• positioning a refractive index matching layer on the mixed liquid crystal unit;
• positioning a mask having a pattern on the first electrode unit or on the second electrode unit;
• forming a wall in a region corresponding to the pattern by polymerizing the first monomer by primary curing of the mixed liquid crystal, the first monomer having a higher diffusion speed and a lower polymerization rate than that of the second monomer;
• and
• forming a network by polymerizing the second monomer by secondary curing of the mixed liquid crystal, the second monomer having a lower diffusion speed and a higher polymerization rate than that of the first monomer,
• wherein the primary curing includes UV irradiation and the secondary curing includes thermal treatment or the secondary curing includes UV irradiation at a wavelength range different from that of the primary curing, and
• wherein the refractive index matching layer has a refractive index in a range of 1.3 to 1.8.

A mixed liquid crystal in which a liquid crystal, a first monomer and a second monomer are dispersed, comprising:

• the first monomer which is configured to be polymerized by initial curing due to a higher diffusion speed and a lower polymerization rate than that of the second monomer so as to form a wall for a light controlling apparatus;
• and
• the second monomer which is configured to be polymerized by subsequent curing due to a lower diffusion speed and a higher polymerization rate than that of the first monomer so as to form a network for the light controlling apparatus,
• wherein the first monomer is UV curable and the second monomer is thermally curable or the second monomer is UV curable at a wavelength range different from that of the first monomer, and
• wherein the mixed liquid crystal is contained in a liquid crystal unit having a refractive index in a range of 1.3 to 1.6 and a refractive index matching layer is positioned on the mixed liquid crystal unit, and
• wherein the refractive index matching layer has a refractive index in a range of 1.3 to 1.8.
