At least one of the color layers contains a compound which is represented by the following general formula (I): In general formula (I), “A” is a substituent group represented by the following general formula (IV):
Claims5
A color filter comprising at least a transparent substrate and color layers disposed on the substrate, wherein at least one of the color layers contains a compound which is represented by the following general formula (I):
- where “A” is a substituent group represented by the following general formula (IV):
- where R21 is an alkylene group containing 1 to 3 carbon atoms and optionally containing, as a substituent group, an alkyl group containing 1 to 4 carbon atoms or an alkoxy group containing 1 to 4 carbon atoms;
- each of R22 and R23 is independently an alkyl group containing 1 to 4 carbon atoms or an alkoxy group containing 1 to 4 carbon atoms;
- “p” is an integer of from 1 to 3;
- each of “q” and “r” is independently an integer of from 0 to 4;

- each of R6 and R7 is independently an alkyl group optionally containing a substituent group or an alkoxy group optionally containing a substituent group;
- Ar1 is a divalent aromatic group optionally containing a substituent group;
- Bc− is a “c”-valent anion;
- “a” is 2;
- “c” is an integer of 2 or more;
- each of “b” and “d” is an integer of 1 or more;
- “e” is 0 or 1;
- each of “f” and “g” is an integer of from 0 to 4;
- each of “f+e” and “g+e” is from 0 to 4;
- R1s may be the same or different;
- R2s may be the same or different;
- R3s may be the same or different;
- R4s may be the same or different;
- R5s may be the same or different;
- R6s may be the same or different;
- R7s may be the same or different;
