Organic light emitting device

An organic light emitting device (OLED) comprising:

• a first electrode;
• a first blue light emitting layer on the first electrode;
• a non-blue light emitting layer on the first blue emitting layer;
• a second blue light emitting layer on the non-blue light emitting layer;
• a second electrode on the second blue light emitting layer;
• and
• a color filter disposed in a path of light emitted from the light emitting layers, wherein the first blue light emitting layer comprises a deep blue dopant, and the second blue light emitting layer comprises a sky blue dopant.

An organic light emitting device (OLED) comprising:

• a first electrode;
• a deep blue light emitting layer on the first electrode;
• a green light emitting layer on the deep blue emitting layer;
• a red light emitting layer on the green light emitting layer;
• a sky blue light emitting layer on the red light emitting layer;
• a second electrode on the sky blue light emitting layer;
• and
• a color filter disposed in a path of light emitted from the light emitting layers.
