ELECTRO-OPTICAL DEVICE AND ELECTRONIC EQUIPMENT

摘要

PURPOSE: An electro-optical device is provided to obtain a high operation performance and a high reliability through a TFT structure for a driving circuit, a pixel section and a memory section formed on a same substrate. CONSTITUTION: Provided are an electro-optical device and an electronic equipment which include the electro-optical device. 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, the 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.
