COLOUR FILTER, COLOUR FILTER ARRAY AND ORGANIC LIGHT-EMITTING DISPLAY DEVICE USING THE SAME

摘要

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