PROBLEM TO BE SOLVED: To provide a photosensitive resin composition that can form a cured film showing high internal quantum efficiency without impairing the original properties of quantum dots; a cured film obtained by curing the photosensitive composition; a light emitting layer for a light emitting display element; a light emitting display element having the light emitting layer; and a method of forming a light emitting layer using the photosensitive composition.SOLUTION: A photosensitive composition contains an alkali-soluble resin (A), a photopolymerizable compound (B), a photopolymerization initiator (C), and a quantum dot (D). The photopolymerization initiator (C) used herein is controlled to have a specific polarization level as a molecule.SELECTED DRAWING: Figure 1 【課題】量子ドットが本来有する特性を損なうことなく、高い内部量子効率を示す硬化膜を形成できる感光性樹脂組成物と、当該感光性組成物を硬化させてなる硬化膜、及び発光表示素子用の発光層と、当該発光層を備える発光表示素子と、前述の感光性組成物を用いる発光層の形成方法とを提供すること。【解決手段】アルカリ可溶性樹脂（Ａ）と、光重合性化合物（Ｂ）と、光重合開始剤（Ｃ）と、量子ドット（Ｄ）とを含む感光性組成物において、分子として、特定の分極度合いに制御されている光重合開始剤（Ｃ）を用いる。【選択図】図１
