Abstract
A color conversion film converts incident light into light with a wavelength longer than that of the incident light. The color conversion film is a laminate film including the following Layer(A) and Layer (B): Layer (A): a color conversion layer as a continuous layer containing at least one organic light-emitting material and a binder resin; and Layer (B): a transparent resin layer with an oxygen permeability of 1.0 cc/m2·day·atm or less.
Claims20
A color conversion film that converts incident light into light with a wavelength longer than that of the incident light, the color conversion film being a laminate film comprising the following Layer (A) and Layer (B):
- Layer (A):
- a color conversion layer as a continuous layer containing at least one organic light-emitting material and a binder resin;
- and
- Layer (B):
- a transparent resin layer with an oxygen permeability of 1.0 cc/m2·day·atm or less,
- wherein:
- the Layer (B) is a cured object layer of a polyol-based resin and a resin composition containing a silicon compound represented by General Formula (6) and a hydrolysate of the silicon compound:
- (R12O4-n—Si-L1-Y)n (6)
- where
- each R12 is independently selected from the group consisting of hydrogen, an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, and a silyl group;
- each L1 is independently selected from the group consisting of a single bond, an alkylene group, and a phenylene group;
- each Y is independently selected from the group consisting of hydrogen, an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, a hydroxy group, a thiol group, a glycidyl group, an alkoxy group, an alkylthio group, a glycidyl ether group, an aryl ether group, an aryl thioether group, an aryl group, a heteroaryl group, halogen, a cyano group, an aldehyde group, a carbonyl group, a carboxy group, an oxycarbonyl group, a carbamoyl group, an amino group, a nitro group, a boryl group, and a phosphine oxide group;
- and
- n is an integer of 0 or more and 4 or less.
A color conversion film that converts incident light into light with a wavelength longer than that of the incident light, the color conversion film being a laminate film comprising the following Layer (A) and Layer (B):
- Layer (A):
- a color conversion layer as a continuous layer containing at least one organic light-emitting material and a binder resin;
- and
- Layer (B):
- a transparent resin layer with an oxygen permeability of 1.0 cc/m2·day·atm or less, wherein
- the organic light-emitting material contains a compound represented by General Formula (1):
- where X is C—R7 or N;
- R1 to R9 are the same as or different from each other, and are selected from hydrogen, an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, a hydroxy group, a thiol group, an alkoxy group, an alkylthio group, an aryl ether group, an aryl thioether group, an aryl group, a heteroaryl group, halogen, a cyano group, an aldehyde group, a carbonyl group, a carboxy group, an oxycarbonyl group, a carbamoyl group, an amino group, a nitro group, a silyl group, a siloxanyl group, a boryl group, a phosphine oxide group, and a condensed ring and an aliphatic ring formed between adjacent substituents.
