Title: The Innovative Contributions of Hiroshi Kuwagaki
Introduction
Hiroshi Kuwagaki is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of liquid crystal display technology, holding a total of 15 patents. His work has been instrumental in advancing display technologies that enhance visual quality and performance.
Latest Patents
Kuwagaki's latest patents include a "Supertwisted nematic liquid crystal device having two phase difference." This invention relates to a liquid crystal display device where phase difference plates, equal in retardation value and composed of uniaxial polymer film, are symmetrically disposed at the front and back sides of an STN liquid crystal panel. This design allows for nearly ideal wavelength dispersion, compensating for phase difference across the entire wavelength region and aligning the azimuth angles of the exit ellipsoidal polarization. As a result, it enables the realization of a colorless display with high contrast.
Another notable patent is the "Liquid crystal display cell and method for manufacturing thereof." This invention involves a liquid crystal display cell utilizing cell substrates made of flexible organic polymer film, with liquid crystals injected between the substrates. The method includes creating a liquid crystal molecule orienting solution with dispersed spacers, applying it to the cell substrates, and sealing the liquid crystals in a space formed between the substrates. This innovative approach allows for the use of thin glass substrates as substitutes for the flexible organic polymer film.
