Abstract
A color filter array is provided that is capable of implementing full color with improved light-emitting efficiency and color coordinate values from a mixed light of blue and red, and an organic light-emitting display device using the same. A color filter array receiving a mixed light of blue wavelength light and red wavelength light to implement full color according to an embodiment of the invention comprises a red filter, a green filter, and a blue filter. The red filter includes a first color conversion material for converting the blue wavelength light into green light and red light and a green blocking material for blocking the green light. The green filter includes a second color conversion material for converting the blue wavelength light into green light and red light and a red blocking material for blocking the red light. The blue filter includes a red blocking material for blocking the red wavelength light.
