Abstract: A display device can include a first light emitting area, a second light emitting area positioned outside the first light emitting area and positioned to be spaced apart from the first light emitting area, a third light emitting area positioned outside the second light emitting area and continuously positioned in contact with the second light emitting area, a second non-light emitting area positioned between the first light emitting area and the second light emitting area, and a first non-light emitting area positioned outside the third light emitting area. As a result, the display device is capable of maximally suppressing a change in color coordinates even at a wide viewing angle.
