Abstract

For our beginning study in large apertures of liquid crystal (LC) lenses, both disclination line and zigzag line are usually occurred in cells. Disclination lines possibly appear and then disappear if we slowly increase applied voltages and/or fabricate LC lens with thicker upper glass substrates. But, zigzag lines always appear near the edges of LC lens. Unfortunately, zigzag lines and disclination lines will possibly link each other, and permanently stay in cells to degrade performance of LC lens. In this paper, we experimentally study and conclude that the suitable rubbing conditions in cells will effectively prevent this problem of linked lines.
