摘要:
A super large wide-angle high-speed response liquid crystal display apparatus manufactured by using a photolithographic procedure for three times. The invention adopts a halftone exposure technology to form a gate electrode, a common electrode, a pixel electrode and a contact pad, and then uses the halftone exposure technology to form a silicon (Si) island and a contact hole, and a general exposure technology to form a source electrode, a drain electrode and an orientation control electrode. A passivation layer uses a masking deposition method. A film is formed by using a P-CVD method, or a protective area is formed at a local area by using an ink coating method or spray method, and a TFT array substrate used for the super large wide-angle high-speed response liquid crystal display apparatus manufactured by using a photolithographic procedure for three times can be produced.
