Abstract

This article describes a new liquid crystal display with a thin film transistor (TFT) array and polymer on array. This display has large viewing angle using pretilt angle control technology, without extra photo process and alignment layer applying process. Figure 1-4 show cross sections of TFT array and liquid crystal cell and their processes. Figure 1. First, ITO is deposited on the substrate. Second, DLC (Diamond like carbon) is deposited. Then, ion beam (IB) is irradiated for liquid crystal alignment process. This ion beam is named is IB1. The direction of IB1 makes the pretilt angle direction of liquid crystal. Figure 2 Coat photo resist and expose it with halftone mask. Then, develop the resist. As a result, Totally-developed
