To provide a photosensitive resin composition from which a barrier wall having excellent curability in a bottom part can be formed even when the photosensitive resin composition has light-shielding property, and to provide a photosensitive element, a barrier wall, a method for forming a barrier wall and a method for manufacturing an image display device using the above composition.

The photosensitive resin composition is used for forming a barrier wall that separates pixels in an image display device, and the photosensitive resin composition comprises: a binder polymer having a carboxyl group in the molecule as (A) component; a photopolymerizable compound as (B) component, a photopolymerization initiator as (C) component, a compound having a mercapto group as (D) component and a black pigment as (E) component.
