Wide Xiewing Angle TFT-LCD Using Inorganic Alignment Layer

Abstract

We have produced prototype TFT-LCD using Surrounding-Electrode method with inorganic alignment layer which rubbed SiNx and so on. These alignment layer is low pretilt-angle, almost 0 degree, available to applied on the Surrounding-Electrode method. These alignment layer is deposited layer, decreasing short-type defects between TFT substrate and counter electrode substrate and on the surface of TFT substrate, and further, enabling to omit TFT passivation. This time, we have evaluated inorganic alignment layer of alignment condition, pretilt-angle, display characteristics and so on.
