Abstract: In a display device, light emitting areas and colored areas each have a predetermined planar shape having no rotational symmetry so that rotation of the area by an angle greater than or equal to 0° but smaller than 360° does not produce an initial shape of the area and are so arranged as to have different types of rotation angle. The colored areas are grouped based on a set of the colored areas of colors different from one another to forma plurality of full-color pixels. The full-color pixels are so arranged that the rotation angle of the colored areas of the same color have different types. In the full-color pixels of the same type, the colored areas of the same color have the same rotation angle. In the full-color pixels of different types, the colored areas of the same color have different rotation angles.
