A photosensitive composition having excellent sensitivity, an insulating film formed using the photosensitive composition, a color filter formed using the photosensitive composition, and the insulating film or the color filter. A display device provided, and a compound suitably blended as a photopolymerization initiator in the photosensitive composition. A photosensitive composition comprising (A) a photopolymerizable compound and (B) a photopolymerization initiator, wherein (B) the photopolymerization initiator contains a compound represented by the following formula (1): Let In formula (1), R 1 is a hydrogen atom, a nitro group or a monovalent organic group, and R 2 and R 3 each have a chain alkyl group which may have a substituent and a substituent. A cyclic organic group or a hydrogen atom, R 2 and R 3 may be bonded to each other to form a ring, R 4 is a monovalent organic group, and R 5 is a hydrogen atom. , An optionally substituted alkyl group having 1 to 11 carbon atoms, or an optionally substituted aryl group, n is an integer of 0 to 4, and m is 0 or 1. .
