Abstract
The present invention provides an active matrix display device capable of raising its integration density by reducing the drive circuit area on the active matrix substrate. A semiconductor film presents in the boundary between a quasi-strip crystalline semiconductor film and another semiconductor film is used to form conductive lines, resistors, source/drain electrodes and the like which are respectively connected to thin film transistors formed using the quasi-strip crystalline semiconductor film.
