The flat display has made remarkable progress in the past 40 years or so, and its applications have expanded to smartphones,
notebook PCs, PC monitors, large flat-panel TVs, VR, and curved displays. Looking at the component inside of these displays,
we can see the adoption of new materials and innovations in manufacturing processes for the commercialization toward to new
applications. In particular, many of the developments in material technology and manufacturing equipment were made by Japan
companies, and Japan companies still occupy a high global market share.
