摘要： A method of production of active matrix display substrates using thin film transistors and more particularly to a method for production of substrates for liquid-crystal display use. The active matrix substrate using the thin film transistor is produced by the mask processes of smaller number. The process of the present invention can reduce the number of the masks, by one, of the active matrix substrate using the inverted staggered thin film transistor which requires the masks from five levels to six levels. Further improvements reduce the number of the masks to four levels from three levels, thus contributing greatly towards lower cost, improved yield.
