Abstract

Disclosed are a color filter including a wavelength conversion layer which converts the wavelength of light, a light transmission layer formed on the wavelength conversion layer, and a wavelength filter layer formed on the light transmission layer, and an image display device. The light transmission layer transmits a light moving between the wavelength conversion layer and the wavelength filter layer and blocks the flow of outgas. The color filter includes the light transmission layer which transmits a light moving between the wavelength conversion layer and the wavelength filter layer and blocks the flow of outgas, thereby capable of achieving high color reproductivity while having excellent light-emitting efficiency and light retention rate.
