Presentations about LCD viewing-angle improvements, evaluations, and TFT-panel testings in 1993 SID international symposium are reviewed. Number of papers about these topics is 6 (19.1〜4,p-49,p-58), 5 (12.4,P-31,P-32.P-51,P-55), and 4 (17.1〜4), respectively. In viewing-angle improvements, modified TN mode and novel LC mode are reported, and optical compensation films are mainly applied in these cases. In viewing-angle evaluations, several graphic visualization methods are proposed to allow intuitive observation. In TFT-panel testings, some in-line panel testing systems designed for lower cost and higher yield of TFT panel are presented.
