摘要：
We propose a novel hybrid aligned liquid crystal (LC) cell with negative dielectric anisotropy of the nematic LC driven by fringe field, which is normally black mode. In the on-state, the dielectric torque between the LC director and horizontal component of the fringe field causes the LC director to rotate in the entire area, so that the cell appears to be white. The device, with a wedge-shaped pixel electrode and optical compensation film, also shows a wide viewing angle, high light efficiency and low driving voltage.
