No. 817: Successful development of the world’s thinnest glass (December 12, 2013)

Nippon Electric Glass developed the world’s thinnest glass for large-scale glass to be incorporated in an organic EL display and solar cell. The thickness is 35 micrometers that is smaller than the diameter of a hair that is 60-90 micrometers. A glass sheet available from other manufacturers is usually 50 micrometers. The new glass is named “G-Leaf.”

The company built the new glass by shaping thinly the glass material founded in the furnace about several tens of meters high using gravity force. It can be shaped to a glass sheet 100 m long and 0.5 m wide. It can be rolled on a cylinder with radium 26 mm. It is suitable for bendable liquid crystal display and touch panel. It can also be used as the substrate glass in the ink-jet type continuous production process of organic EL panel and solar cell. Nippon Electric Glass has already shipped samples of the super thin glass to more than 500 electronic parts manufacturers and manufacturing equipment makers both at home and abroad. Finished products that incorporate the super thin glass will be put on the market in 2015.
