Title: Noboru Kunimatsu: Innovating the Future of Liquid Crystal Display Devices

Introduction:

Meet Noboru Kunimatsu, a brilliant inventor and pioneer in the field of liquid crystal display (LCD) devices. With over 122 patents to his name, Kunimatsu has revolutionized the manufacturing methods and functionalities of LCD technology. Based in Chiba, Japan, Kunimatsu has worked with prestigious companies such as Japan Display Inc. and Panasonic Liquid Crystal Display Co., Ltd.

Latest Patents:

Kunimatsu's latest patents showcase his expertise in developing advanced LCD devices. One notable invention is the manufacturing method of a liquid crystal display device with a photo-alignment treatment. This process involves forming a film containing a light-cleavable polymer, imparting an alignment regulating force through photo-alignment at temperatures lower than 100 degrees Celsius, and removing low-molecular weight components generated during the light irradiation. The result is a high-quality liquid crystal display device that offers improved alignment and performance.

Additionally, Kunimatsu has developed a liquid crystal display device with enhanced pixel electrode connection. By forming a through hole in the organic passivation film and the interlayer insulating film, the pixel electrode can be effectively connected to a source electrode of a thin-film transistor (TFT). The taper angle around the upper base of the through hole is purposefully smaller than the taper angle around the lower base, ensuring smooth alignment film material flow and preventing display defects such as uneven brightness.
