Fast Response and Wide Viewing Angle Vertical Alignment Mode with X-Shape Electrode

Abstract

We proposed the fast response and high transmittance vertical alignment mode by generating the axial symmetry of the liquid crystal (LC) director. To control the LC director, we adopt the x-shaped slit electrode on the only pixel electrode. Using a polymerization of the reactive mesogens (RMs) mixed into the alignment layers, we can memorize the falling direction of LCs and thus the fast switching characteristics can be achieved. Owing to infinite LC domains with the axial symmetry, wide viewing angle characteristics was achieved and high transmittance also was obtained by introducing a quarter wave plate.
