Abstract:
1. A semiconductor device comprising: a pixel portion including a light emitting element; a driver circuit including a buffer portion and a logic portion, which is provided over a substrate; a connecting terminal including a first conductive film over the substrate for supplying a voltage from an external circuit; and a power line electrically connected to the connecting terminal through a contact, wherein the power line is branched at a point of ⅗ or less of a length of the power line from the connecting terminal to the buffer portion, wherein a first line of the power line including a second conductive film is electrically connected to the buffer portion, wherein a second line of the power line including a third conductive film is electrically connected to the logic portion, and wherein the first conductive film, the second conductive film, and the third conductive film are formed in a same film as an electrode of the light emitting element.
