Sumitomo Chemical; Itochu; Toyo Shigyo.Sumitomo Chemical, Itochu and toyo Shigyo Printing jointly announced that they have established a joint venture company in Japan to manufacture and market color filters Color filter An optical element that partially absorbs incident radiation, often called an absorption filter. The absorption is selective with respect to wavelength, or color, limiting the colors that are transmitted by limiting those that are absorbed. for thin film transistor-type liquid crystal displays liquid crystal display (LCD) Optoelectronic device used in displays for watches, calculators, notebook computers, and other electronic devices. Current passed through specific portions of the liquid crystal solution causes the crystals to align, blocking the passage of light. . The new company, called STI STI systolic time intervals. Technology, will produce the 10-inch-diagonal color filters using the pigment-contained color photoresist A film used in photolithography that temporarily holds the pattern of a circuit path or microscopic element of a chip. When exposed to light, it hardens and is resistant to the acid bath that washes away the unexposed areas. Not to be confused with photoresistor. method at a manufacturing facility to be constructed within the confines of Sumitomo Chemical's Ehime Works in Niihama, Ehime Prefecture.
