Claim Text:
1. A method of manufacturing a display device comprising a display unit comprising a plurality of pixels respectively having thin film transistors, and a terminal unit comprising an array of a plurality of terminals, signals to control an operation of the thin film transistors respectively being input into the plurality of terminals; the method comprising: forming a first insulating film on a substrate; forming the thin film transistors on the first insulating film; forming a second insulating film in the display unit and in the terminal unit after the formation of the thin film transistors; forming, in the second insulating film, contact holes each exposing at least a part of a corresponding thin film transistor among the plurality of thin film transistors, while forming a plurality of openings in the second insulating film in the terminal unit; forming, on the second insulating film, a plurality of signal lines respectively connected to the thin film transistors via the contact holes, while forming, on the second insulating film, a plurality of terminal lines with the openings being located therebetween at the same time as the formation of the signal lines; and forming a third insulating film of an organic insulating film on the plurality of signal lines and the plurality of terminal lines.
