<p>PURPOSE: A wiring board for electro-optical device, a circuit board for electro-optical device, an electro-optical device, a manufacturing method thereof, and an electronic device provided to reduce a resistance of a feed line, loss of an electro-luminescent device, and a voltage for driving the electro-luminescent device by improving a structure of the feed line. CONSTITUTION: A wiring board includes an electro-optical element and a driver circuit to drive the electro-optical element. The wiring board includes a feed line film, a signal line film, and an operation line film. The feed line film(32) is used for supplying current to the driver circuit in order to operate the electro-optical element. The signal line film(20) is used for supplying a level signal to the driver circuit in order to determine intensity of the current to be supplied to the electro-optical element. The operation line film(30) is used for supplying an operation instruction signal to the driver circuit in order to instruct whether to operate the electro-optical element. The feed line film is used as a top layer among the feed line film, the signal line film, and the operation line film.</p> |
