Abstract: Semiconductor elements deteriorate or are destroyed due to electrostatic discharge damage. The present invention provides a semiconductor device in which a protecting means is formed in each pixel. The protecting means is provided with one or a plurality of elements selected from the group consisting of resistor elements, capacitor elements, and rectifying elements. Sudden changes in the electric potential of a source electrode or a drain electrode of a transistor due to electric charge that builds up in a pixel electrode is relieved by disposing the protecting means between the pixel electrode of the light-emitting element and the source electrode or the drain electrode of the transistor. Deterioration or destruction of the semiconductor element due to electrostatic discharge damage is thus prevented.

Abstract: To provide a display device which can achieve a reduced frame width and of which the shape of the frame is the same as or similar to the shape of a display region even in the case where the display region has a non-rectangular shape. The display device includes a non-rectangular display region and a driver circuit portion on the periphery of the display region. The driver circuit portion includes at least two gate drivers and at least two source drivers. One of the gate drivers and the other of the gate drivers are arranged to be apart from each other, and one of the source drivers and the other of the source drivers are arranged to be apart from each other.
