Abstract
The homogeneously aligned nematic liquid-crystal (LC) display driven by the fringe-field is known to exhibit high light efficiency as well as a wide viewing angle unlike the conventional in-plane switching (IPS) mode, with pixel and common electrodes existing only on the bottom substrate. We found that when a common electrode exists on the top and bottom substrates, the device with some advantages in fabrication and quality still reveals high transmission and a wide viewing angle with LC having a negative dielectric anisotropy. In this paper, the switching mechanism and electro-optic characteristics of the device with the electrode on the top substrate are investigated.
