AGC Display Glass Yonezawa began manufacturing and processing glass substrates for flat panel displays in 1992 in Yonezawa, known as the "Castle City of Uesugi". Since 2012, the company has been producing and processing cover glass for automotive displays, and was the first in Japan to enable the mass production and processing of glass displays.
In addition to these two core products, the company has also begun manufacturing and processing glass related to semiconductors and electronic components. Under the motto "The basis of production begins with human resource development" and the action guideline "Do and you will achieve" by Lord Uesugi Youzan, a feudal lord of Yonezawa, all employees work as "One Team" and are committed to integrated production.
