Abstract :
In this paper, we propose a dual-view (DV) liquid crystal display (LCD) using blue phase (BP) liquid crystal (LC) in conjunction with the patterned electrode cell. Given the optically isotropic state of the BP LC material, the DV BP LCD is equipped with a low dark state and, therefore, a high contrast ratio that exceeds 1000 in the intended viewing direction. The patterned electrode structure provides inclined electric field parallel to the unintended viewing direction and creates approximately zero phase retardation, thus suppressing light leakage in the unintended viewing direction.
