Abstract

The authors demonstrate a high performance electrically controlled birefringence (ECB) mode with solution-derived La2O3 films at various molar concentrations. Uniform and homogeneous liquid crystal (LC) alignment was spontaneously achieved on the La2O3 films for lanthanum concentrations at ratios greater than and equal to 0.2. A preferred orientation of LC molecules appeared along the filling direction, and the LC alignment was maintained via van der Waals force by nanocrystals of the La2O3 films. The LC alignment mechanism was confirmed by x-ray photoelectron spectroscopy and high-resolution transmission electron microscopy analysis. Superior electro-optical characteristics of the ECB cells constructed with solution-derived La2O3 films were observed, which suggests that the proposed solution-derived La2O3 films have strong potential for use in the production of advanced LC displays.
