抄録	We have newly developed 32 inch-in-diagonal HDTV (1366 x 768 pixels) panels using OCB (Optically Compensated Bend) mode and low temperature p-Si TFT (LTPS)array substrates. The OCB mode can provide advantages both fast response (4ms) and wide viewing angle (> 160 degrees). High performance of brightness of 600 cd/m2 and contrast ratio of 500 :1 w as obtained. By using pseudo-impulse driving method to insert a black period between continuous two frames, moving picture quality was drastically improved [1]. Moving Picture Response Time (MPRT) of 8.4ms was achieved, which was proposed as an indicator of moving picture quality. LTPS array substrates were fabricated in our p-Si line using the largest substrates (730mm x 920mm) and we realized large size and high definition(HD) panels with high performance and high uniformity. By using LTPS, peripheral circuits were integrated on glass substrates. Gate drivers and signal line selectors to reduce the number of external source drivers were integrated, resulting in huge cost reduction and high reliability.
