An organic compound represented by the formula [1]:
R
1
to R
19
are independently selected from the group consisting of a hydrogen atom, a deuterium atom, a halogen atom, and a substituent, and R
9
and R
19
are optionally bonded together. When R
9
and R
19
are bonded together, the bonding is selected from the group consisting of direct bonding, bonding via an oxygen atom or a sulfur atom, and bonding via CR
