Abstract: A highly reliable semiconductor device is provided. The semiconductor device includes first to third transistors and a capacitor. In the first transistor, one of a source and a drain is supplied with a first signal, the other of the source and the drain is connected to a gate of the second transistor and one electrode of the capacitor, and a gate is supplied with a second pulse signal. In the second transistor, one of a source and a drain is supplied with a first pulse signal, and the other of the source and the drain is connected to the other electrode of the capacitor and one of a source and a drain of the third transistor. In the third transistor, the other of the source and the drain is supplied with the first potential, and a gate is supplied with a second signal that is an inverted signal of the first signal. The first pulse signal is a clock signal, and the second pulse signal has a duty ratio of 55% or lower.

Abstract: To suppress a variation in characteristics of a transistor due to a released gas from an organic insulating film so that reliability of a display device is increased. The display device includes a transistor, an organic insulating film which is provided over the transistor in order to reduce unevenness due to the transistor, and a capacitor over the organic insulating film. An entire surface of the organic insulating film is not covered with components (a transparent conductive layer and an inorganic insulating film) of the capacitor, and a released gas from the organic insulating film can be released to the outside from exposed part of an upper surface of the organic insulating film.

Abstract: A highly reliable semiconductor device or display device is provided. The semiconductor device has a function of inhibiting hot-carrier degradation of a transistor and includes a switch which includes a plurality of transistors connected in series and a diode connected to a node between the transistors. An appropriate potential supplied from the diode to the node can lower a source-drain voltage before the transistor is turned on, so that hot-carrier degradation can be inhibited.
