TOKYO -- May 20, 2013

AGC, a world-leading manufacturer of glass, chemicals and high-tech materials,
announced today that the Company will release its new self-adhesive glass for
optical bonding that bonds directly to display devices used in tablets and
other electronic products. The product, which significantly simplifies the
process of bonding cover glass directly to display devices, will greatly
contribute to the proliferation of more vivid and clear displays. Optical
bonding optimizes the refractive index of resin to minimize the loss of light
for enhanced visibility.

Samples of AGC's self-adhesive glass for optical bonding will be displayed at
Society for Information Display (SID) in Vancouver from May 20.

As a technology to improve the display quality of mobile devices and others,
bonding cover glass directly to the display is on the verge of gaining wide
popularity. Direct bonding realizes high contrast images by minimizing
reflection while enhancing image sharpness, but it also has the drawbacks of
requiring high-temperature, high-pressure processing and the curing process of
the resin. In addition, the quality is particularly prone to be ununiform in
midsize and large liquid crystal displays (LCDs) when direct bonding is used.

In response, AGC's new cover glass has enabled the direct bonding of cover
glass and display devices without creating a void by using a newly-designed
resin for bonding that is set on the bonding surface. Any air bubbles that
form during the bonding process are automatically absorbed in the resin.
Bonding using this product does not require complex processing, such as
high-temperature, high-pressure treatment, so processing can be accomplished
with a much simpler methodology. Also, the productivity is largely superior to
conventional processing methods, and the process is expected to be applied to
even larger displays.

The new product also is suitable for IPS-mode LCDs, of which image quality is
prone to be ununiform due to the pressure created when the cover glass is
bonded to the LCDs. IPS stands for In-Plane Switching, a type of liquid
crystal display that is increasingly being used in mobile handsets. Going
forward, AGC's new cover glass is expected to be used in these and many other
types of LCDs.

Looking ahead, AGC expects to develop new products and technologies for
increasingly sophisticated displays by integrating diverse glass and chemical
technologies for glass materials design and processing, organic materials and
coating.
