Title: Motohiko Yoshida: Innovator in Electrophoretic Display Technology

Introduction

Motohiko Yoshida is a prominent inventor based in Hamura, Japan. He has made significant contributions to the field of display technology, holding a total of five patents. His work focuses on advancements in electrophoretic display devices and thin film transistors.

Latest Patents

One of Yoshida's latest patents is for an electrophoretic display device. This device includes a first substrate and a second substrate arranged opposite each other at a predetermined interval. It features a plurality of pixel electrodes aligned on the first substrate, with wiring arranged between adjacent pixel electrodes. An opposite electrode is provided on the second substrate, along with a partition wall that surrounds the pixel electrodes. The partition wall has a rectangular shape, with at least one side featuring an expanded-width portion. Additionally, a solvent fills the space surrounded by the partition wall, dispersing a plurality of particles.

Another notable patent involves a manufacturing method for thin film transistors that includes low resistance conductive thin films. This method consists of forming a pair of source/drain electrodes on a substrate, defining a gap between them. Low resistance conductive thin films are then formed on the source/drain electrodes, and an oxide semiconductor thin film layer is created on the upper surface of these films. The process ensures that the side surfaces of the conductive thin films and the oxide semiconductor thin film layer align in the channel width direction.
