Latest Patents

One of his latest patents is for an in-plane switching mode active matrix type liquid crystal display device and method of fabricating the same. This innovative device includes a first substrate and a second substrate located opposing the first substrate, with a liquid crystal layer sandwiched between them. The first substrate features a thin film transistor, pixel electrodes associated with each pixel, a common electrode for reference voltage, data lines, a scanning line, and common electrode lines. The molecular axes of the liquid crystal are rotated in a plane parallel to the first substrate by an electric field, allowing for the display of images. The common electrode is made of transparent material and is positioned closer to the liquid crystal layer than the data lines. It entirely overlaps the data lines, except in areas near the scanning line. Additionally, the device includes a light-impermeable layer in regions where the common electrode overlaps the data lines, which is comprised of a black matrix layer narrower than the common electrode.
