Organic light emitting display apparatus

A display apparatus, comprising:

• a substrate including a plurality of pixel areas;
• a pixel electrode on the substrate;
• an opposite electrode on the pixel electrode;
• a main light emitting layer between the pixel electrode and the opposite electrode, the main light emitting layer emitting a first light having a first wavelength;
• a sub light emitting layer on the substrate, the sub light emitting layer absorbing a portion of the first light and emitting a second light having a second wavelength greater than the first wavelength;
• and
• a sealing layer on the sub light emitting layer, wherein an air-gap does not exist between the sub light emitting layer and the sealing layer.

A display apparatus, comprising:

• a substrate including a red pixel area and a green pixel area;
• a pixel electrode on the substrate;
• an opposite electrode on the pixel electrode;
• a main light emitting layer between the pixel electrode and the opposite electrode, the main light emitting layer including a first organic light emitting layer in the red pixel area and a second organic light emitting layer in the green pixel area, and each of the first organic light emitting layer and the second organic light emitting layer including a material emitting a blue colored light;
• and
• a sub light emitting layer on the substrate, the sub light emitting layer absorbing a portion of the blue colored light and emitting a light having a wavelength greater than that of the blue colored light,
• wherein the sub light emitting layer includes a first light emitting layer in the red pixel area and a second light emitting layer in the green pixel area,
• a light emitted from the first organic light emitting layer and passing through the first light emitting layer has a red color;
• and
• a light emitted from the second organic light emitting layer and passing through the second light emitting layer has a green color.
