Display device

A display device comprising:

• a display element;
• a color conversion layer on the display element and comprising first to third color conversion parts each of which comprises a quantum dot and that are located to be spaced apart from each other;
• an encapsulation member between the display element and the color conversion layer comprising an inorganic layer contacting the color conversion layer;
• and
• a buffer layer between the encapsulation member and the color conversion layer, the buffer layer having a refractive index of 1.5 to 2.0.

A display device comprising:

• a display element comprising first to third pixel regions adjacent to each other in a plane, the display element comprising a first organic light emitting diode overlapping the first pixel region and comprising a light emitting layer, a second organic light emitting diode overlapping the second pixel region and comprising a light emitting layer, and a third organic light emitting diode overlapping the third pixel region and comprising a light emitting layer;
• an encapsulation member on the display element and comprising an inorganic layer at an outermost portion thereof;
• a color conversion layer on the encapsulation member and comprising a first color conversion part located to correspond to the first organic light emitting diode, a second color conversion part located to correspond to the second organic light emitting diode, and a third color conversion part located to correspond to the third organic light emitting diode;
• a color filter layer on the color conversion layer;
• a buffer layer between the encapsulation member and the color conversion layer, wherein a difference in refractive index between the buffer layer and the inorganic layer is 0.5 or less;
• a low-refractive index layer between the color conversion layer and the color filter layer;
• a first capping layer between the color conversion layer and the low-refractive index layer;
• and
• a second capping layer between the buffer layer and the color conversion layer,
• wherein the light emitting layers of the first organic light emitting diode, the second organic light emitting diode, and the third organic light emitting diode are integrated with each other.
