A joint research group of AIST-Photonics Research Institute (AIST-PRI), Hitachi Ltd. and OITDA has developed a printed protective layer that keeps the transistor from damage during pixel formation with liquid crystals and source and drain electrodes which reduce the contact resistance for organic thin film transistors (OTFT). They have also succeeded in producing a 1.4-inch color liquid-crystal display with a resolution of 80 pixels/inch driven by the OTFT prepared by using the developed techniques. These techniques are expected to act as a breakthrough for the development of a low-cost flexible display such as an e-paper.
