Abstract

We analyzed the lowering of transmittance due to lateral field effect in the edge of pixel. We studied the method to solve the problem of VA-LCD. It occurred director distortion and transmittance lowering by strong lateral field in the edge of pixel. For analyzing the director distortion and improving the transmittance lowering, we applied the edge pattern to PVA-LCD of cross pattern. As a results, transmittance in the new VA modes were higher than that of conventional VA modes.
