Latest Patents
One of Itoh's latest patents is for an inorganic thin film polarizer. This innovative polarizer features a matrix composed of fine columns arranged on a substrate, with light-absorbing portions provided on the columns. The columns are made of an inorganic substance that is transparent in various wavelength regions, including visible light, ultraviolet, and infrared. Each column has a circular cross-section and is tilted at a constant angle, providing anisotropy in density. The light-absorbing portions have a higher light extinction coefficient than the columns, ensuring effective polarization.
Another significant patent by Itoh involves a liquid crystal device with an oblique evaporation film. This device is designed to have higher durability and improved display quality, making it suitable for applications such as glare shield reflection mirrors. The device consists of a pair of substrate plates with a liquid crystal layer in between, and an oblique evaporation film laminated on one of the plates. A protective layer is formed at the boundary surface, preventing issues such as bluish oblique evaporation films caused by proton intrusion from neighboring materials.
