Color conversion panel and display device including the same

A display device, comprising:

• a display panel;
• and
• a color conversion panel overlapping the display panel,
• wherein the color conversion panel comprises:
• a substrate comprising a light blocking area and a first transmission area, a second transmission area, and a third transmission area;
• a first color filter disposed on the substrate in the first transmission area;
• a second color filter disposed on the substrate in the second transmission area;
• a low refractive index layer disposed on the substrate and the first and second color filters in the light blocking area and the first, second, and third transmission areas;
• a first color conversion layer disposed on the low refractive index layer above the first color filter;
• a second color conversion layer disposed on the low refractive index layer above the second color filter;
• and
• a light transmitting layer disposed on the low refractive index layer in the third transmission area, and
• wherein:
• the low refractive index layer has a refractive index lower than a refractive index of the first color conversion layer and a refractive index of the second color conversion layer;
• and
• a color filter is absent in the third transmission area.

A display device, comprising:

• a substrate comprising a light blocking area and a first transmission area, a second transmission area, and a third transmission area;
• organic light emitting elements disposed on the substrate at each of the first, second, and third transmission areas;
• a thin film encapsulation layer disposed on the organic light emitting element;
• a first color conversion layer disposed on the thin film encapsulation layer in the first transmission area;
• a second color conversion layer disposed on the thin film encapsulation layer in the second transmission area;
• a light transmitting layer disposed on the thin film encapsulation layer in the third transmission area;
• a low refractive index layer disposed on the first color conversion layer, the second color conversion layer, and the light transmitting layer;
• a first color filter disposed directly on the low refractive index layer above the first color conversion layer;
• and
• a second color filter disposed directly on the low refractive index layer above the second color conversion layer,
• wherein:
• the low refractive index layer has a refractive index lower than a refractive index of the first color conversion layer and a refractive index of the second color conversion layer;
• and
• a color filter is absent in the third transmission area.
