Abstract
Plastic LCDs have remarkable advantages as compared to glass LCDs, but there still exist reliability issue. Regarding the reliability issue of plastic LCDs, we investigated the phenomena of dark spots that often occurred in plastic LCDs. It was recognized that dark spots are mainly caused by air bubbles that are induced from outside of LCD panel due to cell volume change with external stress and incomplete encapsulation. We have found that cell gap uniformity, spacer density and size and film deformation are important factors influencing dark spot behavior. In this paper, we discuss the phenomena and origin of dark spots in plastic LCDs
