Abstract:
1. A method of manufacturing an electro-optical device, comprising: forming data lines that extend in a certain direction and scanning lines that extend orthogonal to the data lines in an image display region on a substrate; forming switching elements to which scanning signals are supplied by the scanning lines; forming pixel electrodes to which image signals are supplied by the data lines via the switching elements; forming driving circuits to drive the data lines and the scanning lines in a peripheral region around the image display region; forming an interlayer insulating film on the data lines, the scanning lines, the switching elements, and the driving circuits; etching portions of the interlayer insulating film corresponding to regions in which the driving circuits are formed in the interlayer insulating film formed in the peripheral region, while excluding portions of the interlayer insulating film corresponding to the image display region from the etching process; and performing a planarizing process on the interlayer insulating film of both the peripheral region and the image display region after the etching.
