The invention relates to a display device, an electro-optical device, electric equipment, a metal mask, and a pixel array. The display device includes a plurality of pixels, each of the pixels including sub-pixels of a first color, a second color and a third color, the sub-pixels of first and second color are arranged in a column direction, and the sub-pixel of third color is arranged in a row direction with respect to the sub-pixels of first and second colors. The pixels adjacent to each other in the column direction form a set of an even row and a next odd row in an even column, and form a set of an odd row and a next even row in an odd column, in the two sub-pixels of third color, a light emitting layer is continuous and light emitting regions are separated from each other, and the light emitting regions are disposed to be line symmetric with respect to a center line partitioning the two sub-pixels of third color.
