Abstract

See full text

An active matrix display device having low resistance additional capacitor common lines and additional capacitors in which each of the additional capacitors has a first electrode connected to a switching element and a second electrode connected to the additional capacitor common line, and the additional capacitor common line is made of the same material as the signal lines, so that the possibility of signal delay on the additional capacitor common lines is reduced.
