Abstract:
A method of manufacturing an active matrix type display device, said method comprising the steps of:forming at least an inverted stagger thin film transistor on an insulating surface; forming a first interlayer insulating film to cover the inverted stagger thin film transistor; forming a second interlayer insulating film to cover the first interlayer insulating film; forming at least a black mask to cover the second interlayer insulating film; forming an inorganic layer to cover the black mask; selectively removing the black mask and the inorganic layer; forming a third interlayer insulating film to cover the black mask and the inorganic layer; selectively removing the third interlayer insulating film to expose a portion of the inorganic layer; and forming a transparent conductive film to cover the third interlayer insulating film, wherein an auxiliary capacitance is formed between the black mask and the transparent conductive film with the portion of the inorganic layer interposed therebetween.
