Abstract
Abstract In a thin-film transistor array, a plurality of gate buses and a plurality of source buses are formed on a substrate in such a manner that said gate buses are intersected with said source buses at crossover portions, and a plurality of thin-film transistors are formed on the substrate adjacent to the crossover portion, which are connected to the gate buses and source buses for a driving purpose. Furthermore, an auxiliary bus is formed on either the gate buses, or source buses, shortcircuited portions of which are cut out by means of laser trimming so as to conduct the gate buses or source buses.
