2. Description of the Related Art
As a means of downsizing, weight saving, and obtaining a narrowed bezel of a flat panel display typified by a liquid crystal display device and a light-emitting display device, it is known that a gate driver and a pixel portion are formed on one substrate. To obtain a bezel which is further narrowed, downsizing of the gate driver is required. Main circuits of the gate driver include a shift register.
