Abstract

See full text

A color conversion filter contains at least one kind of squarylium dye that radiates fluorescence light, has a wavelength conversion capability, absorbs light in an unneeded wavelength region, radiates fluorescence light in a preferable wavelength region, and does not allow decrease in brightness, and thus is preferable for color conversion light-emitting devices, photoelectric conversion devices and the like. Specifically, the color conversion filter has an absorption having a high intensity in the range of 570 to 600 nm, and thus is preferable for use in a color conversion filter that radiates fluorescence light having a high intensity in the range of 600 to 780 nm.
