On April 14, 2004, ZEON Corporation (President and CEO: Naozumi Furukawa; Chiyoda-ku, Tokyo) celebrated the completion of a facility to process diffusion plates for liquid crystal displays (LCDs) made from Cyclo-Olefin Polymer (COP) at its Takaoka Plant (Takaoka City, Toyama Prefecture). Following the completion of this facility and clean rooms, molders will be installed, and manufacture of diffusion plates is schedule to begin from the middle of May, 2004.
ZEON Corporation invested approximately 1 billion yen, and initial production capacity will start at one million units annually, planning to gradually increase production in the future. Diffusion plate sales for this fiscal year are estimated at 1 billion yen.
Optes Co., Ltd. (President: Masahiro Yamazaki; Sano City, Tochigi Prefecture), a wholly owned subsidiary of ZEON Corporation, began manufacturing and marketing ZEONOR COP diffusion plates in fiscal year 2003. Optes Co., Ltd. will operate the new full-scale diffusion plate facility. Demand for LCDs used in personal computer monitors and large screen televisions has been rapidly expanding in recent years. LCDs require the use of a light source, and diffusion plates are used in backlight LCDs to disperse light uniformly.
ZEONOR has the following superior features:
- Low water absorbency reduce the possibility of warping when used for large-sized diffusion plates of over 20 inches.
- Due to its low specific gravity, light-weight diffusion plates can be easily produced.
- Since ZEONOR does not easily warp, diffusion plates can be made thinner.
- Because of its high fluidity when heated and melted, it can be used for injection molding, and can be molded into complicated shapes.
ZEON Corporation and Optes Co., Ltd. plan to continue expanding and fostering the COP precision processing business, and will enhance the Takaoka Plant into a large-scale base for precision processing, mainly for the diffusion plates and ZEONOR film, and LCD optical film, which is already in production.
