Negative photosensitive resin composition, cured product, and method for producing patterned cured product

The invention relates to a negative photosensitive resin composition, a cured product, and a method for producing a patterned cured product. The present invention addresses the problem of providing: a negative-type photosensitive resin composition capable of forming a patterned cured film having a high refractive index and a convex lens shape; a cured product of the negative-type photosensitive resin composition; and a method for producing a cured product using the negative-type photosensitive resin composition. [Solution] A negative photosensitive resin composition containing a resin (A) having a specific structure, a photopolymerization initiator (C), and a compound (D) having a specific structure; a cured product of the negative photosensitive resin composition; and a method for producing a patterned cured film using the negative photosensitive resin composition. 本发明涉及负型感光性树脂组合物、固化物及经图案化的固化物的制造方法。本发明的课题是提供能够形成具有高折射率并且具有凸透镜形状的经图案化的固化膜的负型感光性树脂组合物、该负型感光性树脂组合物的固化物、及使用前述的负型感光性树脂组合物的固化物的制造方法。本发明的解决手段为：包含特定结构的树脂(
