Latest Patents

Watanabe holds a patent for a "Method of manufacturing color filters." This patent outlines a detailed process that includes several steps. First, a plurality of transparent electrodes is formed on one surface of a transparent board. Next, color filters of various colors are stacked on these electrodes in a predetermined sequence. A high-energy beam is then scanned at fixed pitch intervals to selectively remove the transparent electrodes and color filters. Following this, a black resist is coated onto the surface of the transparent board, and light is irradiated from the back to expose the black resist layer. Finally, the exposed board is developed to remove the unexposed black resist, forming a light-shielding film around the color filter. This method allows for improved processing quality, especially when using laser light with a short wavelength of 380 nm or less.
