Abstract
An electro-optical device having high operation performance and high reliability, and electronic equipment which include the electro-optical device, are provided. A TFT structure that is strong against hot carrier injection is realized by placing an LDD region which overlaps a gate electrode in an n-channel TFT forming a driver circuit. Furthermore, a TFT structure having a low off current value is realized by placing LDD regions which do not overlap a gate electrode in a pixel TFT forming a pixel section. In addition, the electro-optical device has a memory section on the same insulator, the memory section having a memory transistor and storing data.
