Abstract
An optical film includes a selective visible light-absorbing layer including at least one dye having a maximum absorption wavelength in a range of about 470 nm to about 510 nm, the selective visible light-absorbing layer having a maximum light transmittance of about 60% or less at the maximum absorption wavelength of the dye and a full width at half maximum of about 50 nm or less.
Claims17
An optical film, comprising a selective visible light-absorbing layer including at least one dye having a maximum absorption wavelength in a range of about 470 nm to about 510 nm, the selective visible light-absorbing layer having a maximum light transmittance of about 60% or less at the maximum absorption wavelength of the dye and a full width at half maximum of about 50 nm or less, wherein the dye includes a cyanine dye.
An optical filter, comprising at least one layer, wherein:
- the layer includes at least one dye having a maximum absorption wavelength in a range of about 470 nm to about 510 nm,
- the layer has a maximum light transmittance of about 60% or less at the maximum absorption wavelength of the dye and a full width at half maximum of about 50 nm or less, and
- the dye includes a cyanine dye.
A display device, comprising an optical filter having at least one layer, wherein:
- the layer includes at least one dye having a maximum absorption wavelength in a range of about 470 nm to about 510 nm,
- the layer has a maximum light transmittance of about 60% or less at the maximum absorption wavelength of the dye and a full width at half maximum of about 50 nm or less, and
- the dye includes a cyanine dye.
