1-10. (canceled)
A Schiff base type compound represented by general formula (I′):
- wherein ring A′ represents an aromatic ring, an aliphatic ring, or a heterocyclic ring;
- Ar′ represents a 5- or 6-membered heterocyclic or aromatic ring;
- and X′ represents a halogen atom, the aliphatic ring represented by ring A′ and the aromatic ring and the heterocyclic ring represented by ring A′ or Ar′ being optionally fused to a ring or optionally substituted, at least one of the hydrogen atoms bonded to ring A′ or Ar′ being displaced by an amino group represented by —NR″R′″ (wherein R″ and R′″ each represent an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 10 carbon atoms and may be each taken together with ring A′ or Ar′ to form a ring structure).
A color conversion layer comprising a coloring material comprising at least one Schiff base type compound represented by general formula (I):
- wherein ring A represents an aromatic ring, an aliphatic ring, or a heterocyclic ring;
- Ar represents a 5- or 6-membered heterocyclic or aromatic ring;
- and X represents a halogen atom, the aliphatic ring represented by ring A and the aromatic ring and the heterocyclic ring represented by ring A or Ar being optionally fused to a ring or optionally substituted.
A light absorbing layer comprising a coloring material comprising at least one Schiff base type compound represented by general formula (I):
- wherein ring A represents an aromatic ring, an aliphatic ring, or a heterocyclic ring;
- Ar represents a 5- or 6-membered heterocyclic or aromatic ring;
- and X represents a halogen atom, the aliphatic ring represented by ring A and the aromatic ring and the heterocyclic ring represented by ring A or Ar being optionally fused to a ring or optionally substituted.
