|Section2= |Section3= }} ''para''-Azoxyanisole (PAA) is an organic, aromatic compound. In a solid state, it appears as a white powder, but when heated it forms a liquid crystal. As one of the first known and most readily prepared liquid crystals, PAA has played an important role in the development of liquid crystal displays.〔''Liquid Gold: The Story of Liquid Crystal Displays and the Creation of an Industry'', Joseph A. Castellano, ISBN 978-981-238-956-5〕 Its liquid crystal range is from 118 °C to 136 °C. The solid to nematic transition is at 118 °C and the nematic to isotropic liquid transition at 136 °C.〔 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Para-Azoxyanisole」の詳細全文を読む スポンサード リンク
