Abstract: A display device includes a pixel electrode, a pixel isolation insulating film in which an opening through which the pixel electrode is exposed at a bottom is formed, and a light-emitting layer formed inside the opening. The pixel isolation insulating film contains particles that receive light emitted from the light-emitting layer and propagate light in a direction different from that of the light emitted from the light-emitting layer.

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.
