The purpose of the present invention is to provide a photosensitive composition having excellent sensitivity, an insulating film formed using said photosensitive composition, a color filter formed using said photosensitive composition, a display device provided with said insulating film or said color filter, and a compound suitable for incorporation as a photopolymerization initiator into said photosensitive composition. This photosensitive composition includes (A) a photopolymerizable compound and (B) a photopolymerization initiator, wherein the photopolymerization initiator (B) contains a compound represented by formula (1). In formula (1), R
1
is a hydrogen atom, a nitro group, or a monovalent organic group; R
2
and R
3
are each an optionally substituted linear alkyl group, an optionally substituted cyclic organic group, or a hydrogen atom, and R
2
and R
3
may be bonded to one another to form a ring; R
4
is a monovalent organic group; R
5
is a hydrogen atom, an optionally substituted C1-11 alkyl group, or an optionally substituted aryl group; n is an integer from 0 to 4; and m is 0 or 1.
