Abstract
Flexible displays recently attract a great deal of attention as next-generation technology to create various electronic display styles. We have been developing organic light emitting diodes (OLEDs), liquid crystal (LC) devices, organic thin film transistors (OTFTs) on plastic substrates, to realize a flexible thin light-weight display for moving images. In flexible OLED devices, phosphorescent polymers were introduced into light emitting layers with high efficiency. In flexible LC devices, a fast-response LC/polymer composite film was formed to keep substrate gap constant. To drive these display devices, we also fabricated low-voltage OTFT array on the plastic substrate. We have demonstrated flexible color active-matrix displays of OLED and LC based on the OTFT technology.
