1. An organic light emitting display panel comprising:
a substrate including an active area that displays an image and a non-active area that does not display the image;
a transistor in the active area of the substrate:
an insulating film over the transistor in the active area of the substrate, the insulating film including a concavity; and
a sub-pixel electrically connected to the transistor, the sub-pixel including a plurality of light emitting areas and a non-light emitting area, the non-light emitting area between the plurality of light emitting areas;
wherein the sub-pixel comprises a first electrode, an organic layer, and a second electrode, the organic layer including a light emitting dopant with a full width at half maximum (FWHM) of 64 nm or less.
