Conventionally, a photocurable composition to which an ultraviolet absorber is added is difficult to form a colorless and transparent cured resin because the ultraviolet absorber itself is colored, and thus the photocurable composition is hardly to be used in a display apparatus required for colorlessness and transparency. Provided is a photocurable composition including a specific compound, wherein a light transmittance of 385 nm is 50% or less and a yellowness index is 3.0 or less in a state in which a cured resin having a thickness of 200 μm or less is interposed between alkali free glass plates each having a thickness of 0.7 mm.
