High-transmittance liquid crystal cell fabricated using nanoparticle-doped polyimide

We found that we can increase the transmittance of a liquid crystal (LC) cell by doping the alignment material with nanoparticles. We fabricated an LC cell using indium-tin-oxide glass substrates coated with SiO 2 -doped polyimide. We confirmed that the transmittance of LC cells fabricated using SiO...

Description
Summary:We found that we can increase the transmittance of a liquid crystal (LC) cell by doping the alignment material with nanoparticles. We fabricated an LC cell using indium-tin-oxide glass substrates coated with SiO 2 -doped polyimide. We confirmed that the transmittance of LC cells fabricated using SiO 2 -doped polyimide was higher than that of LC cells fabricated using pure polyimide. To account for the increase of transmittance, we measured the order parameter of the fabricated LC cells and investigated the surface morphology of the alignment layer using atomic force microscopy.
