Abstract:
1. A semiconductor device comprising: a capacitor element; a first transistor; a second transistor; a third transistor; and a fourth transistor, wherein a first electrode of the capacitor element is electrically connected to a gate of the first transistor, wherein one of a source and a drain of the second transistor is electrically connected to the gate of the first transistor, and the other of the source and the drain of the second transistor is electrically connected to one of a source and a drain of the first transistor, wherein one of a source and a drain of the third transistor is electrically connected to the one of the source and the drain of the first transistor, wherein one of a source and a drain of the fourth transistor is electrically connected to a second electrode of the capacitor element, and wherein an area of the first electrode of the capacitor element is larger than an area of a channel region of the first transistor.
