Display device having a switch with floating regions in the active layer |
摘要 |
A display device having high definition and high reliability, and technology for manufacturing the same. In an active matrix type display device of integrated peripheral driving circuit type, pixel TFTs of an active matrix circuit 100 are not provided with LDD regions. Also, among circuits constituting peripheral driving circuits 101, 102, buffer circuits, of which a high withstand voltage and high-speed operation are required, are made with thin film transistors having floating island regions and base regions between source and drain regions of their active layers.
