An organic compound that absorbs light of a wavelength range from 450 nm to 580 nm in a reduction state and is colored and that is superior in high-temperature drive durability and that is expressed by the following formula [1].




Z1 and Z2 each represent a substituent. R11 to R18 each represent a hydrogen atom or a substituent. R12 and R13 are optionally bound to each other to form a ring. R21 and R22 each represent a hydrogen atom or a substituent. X− represents an anion, and n is an integer greater than or equal to 1. When n is 2 or greater, two or more X−s are the same or different from each other.
