| Abstract: | 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 SiO2-doped polyimide. We confirmed that the transmittance of LC cells fabricated using SiO2-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. |
