Responding to Global Needs: The history of NEG

NEG was founded over half a century ago, in 1949. In the intervening years, the company has consistently focused on developing and improving its glassmaking technology and introducing new products. NEG has always been committed to creating and refining its technology. In addition to the production facilities in Japan that constitute its core base, NEG has established plants overseas to meet global needs. The company has also been transforming its business structure in order to adapt to new market conditions. NEG will continue to draw on its extensive expertise and seek to manufacture products of the highest standards.

1944-1959 Creating NEG’s Foundations

In 1949, the company was separated from NEC and founded as NEG, with a focus on hand-blown vacuum bulbs and glass tubing. In 1951, NEG succeeded in automating the production of glass tubing by the Danner process. In 1956, continuous production of glass tubing began, using a tank furnace, and glass tubing became the foundation of the company.


1960-1989 The Age of CRTs

Production of CRT glass bulbs was started in 1965. The company entered a period of growth that reflected the development of television and CRT-related business in Japan. This period saw the start of production of glass-ceramics, glass blocks for construction, electronic glass materials, and glass fiber. NEG grows into one of the world’s leading manufacturers of specialty glass, with CRT glass becoming one of its core products.


1990-1999 Age of Overseas Development

Entering the 1990s, NEG began to put together a global production network in response to the overseas expansion of Japanese CRT manufacturers and growing global demand. Flat panel displays began to appear in the latter half of 1990s, and the company started producing substrate glass for LCDs and PDPs by the overflow and float processes, respectively.


2000-2009 The Age of FPDs

To meet the rapid increase of the FPD market, we started producing glass substrates for LCDs using the overflow process. We made efforts to match the advanced requirements of the FPD market, such as making larger and higher-quality glass substrates.


2010-2014 Creating a new business pillar for growth

With the deceleration of FPD glass sales, we expanded our glass fiber for reinforcing high-function engineering plastics, and glass tubing for pharmaceutical and medical use. We also launched various new products, such as glass for solar cells, cover glass for smartphones, and phosphor-glass composite. We also made progress in developing unique products, such as glass-ribbon and glass with a CTE(coefficient of thermal expansion)of zero.


2015- For further growth

To seek further growth, we revised our corporate philosophy in 2015 and embarked on a three-year medium-term business plan in 2016. Under these circumstances, to expand our glass fiber business, we acquired a European business in 2016 and an American business in 2017 from PPG Industries. As a result, glass fiber has joined FPD glass as one of our main businesses supporting the company.
