Composition and manufacturing method thereof, hardened film, and display device

Abstract

The object of the present invention is to provide a composition exhibiting good process suitability, a hardened film formed from the composition, and a display device comprising the hardened film. A composition comprises semiconductor particles (A), a resin (C), and a polymeric compound (D), wherein the polymeric compound (D) contains a polymeric compound (Da) having a functional group exhibiting coordination ability, and the value RDf / A expressed by the following formula is less than 0.6: RDf / A = RDf / RA (where RA represents the content (mass) of semiconductor particles (A) in the composition, and RDf represents the content (mass) of polymeric compound (Df) in the composition as polymeric compound (D) not coordinated to semiconductor particles (A)).
