With an impressive portfolio of 43 patents, he has played a critical role in advancing innovation in display devices, particularly through his recent inventions that enhance the performance and reliability of LCDs.

Latest Patents

Among Matsumori's latest inventions is a novel liquid crystal display device and its manufacturing method. This cutting-edge innovation addresses a common issue in LCDs utilizing the in-plane switching (IPS) method by preventing the shaving of an alignment film caused by a columnar spacer. The design introduces a plinth that is higher than the pixel electrode, which ensures a more uniform application of a double-layered alignment film. The technique improves the quality of the alignment film through a leveling effect, allowing a photodegraded upper alignment layer to dissolve and leave a robust lower alignment layer intact. These advancements lead to enhanced durability and functionality in liquid crystal display devices.

Another critical patent describes a liquid crystal display device featuring a TFT substrate equipped with a first alignment film and an opposing substrate with a second alignment film. This configuration effectively sandwiches liquid crystals between the layers. Importantly, one of the alignment films is made up of a specific polyimide formulation, demonstrating a clever adaptation of materials to improve response to photo-alignment, thereby optimizing the performance of the display.
