In this manner, even when a patterning precision for forming a semiconductor element and a wiring finer is improved, high definition of a display device having a light emitting element is not expected since the intervals between the apertures of the metal mask cannot be narrow. In view of the aforementioned problem, according to the invention, element forming regions of the same color are disposed diagonally and a pixel portion has a structure that a region for forming an element are shared by a plurality of pixels. A specific pixel structure of the invention is that element forming regions of a first color, a second color, and a third color are each disposed diagonally and three or more element forming regions are shared by each pixel. |
