Latest Patents

Atsushi Ohta holds a patent for a "Method for producing color filter, color filter, liquid crystal display device and producing apparatus." This invention focuses on preventing the exfoliation of an etching stopper. The color filter includes an inorganic protection film composed mainly of SnO. This film not only exhibits high specific resistance but also has a linear expansion coefficient that closely matches that of a transparent electrode. As a result, the inorganic protection film remains intact even when subjected to heat during processing. Additionally, the ability to form both the inorganic protection film and the transparent electrode in the same film forming chamber significantly reduces the production time compared to conventional techniques. He has 1 patent to his name.
