Abstract
Provided is a layered structure having a first electrode, a second electrode, a light emitting layer or a charge separation layer located between the first electrode and the second electrode, and a layer located between the light emitting layer or the charge separation layer and the first electrode and containing a polymer having a repeating unit containing one or more ionic groups selected from two specific groups and one or more specific polar groups. Also provided is a polymer having, as the repeating unit containing one or more ionic groups selected from two specific groups and one or more specific polar groups, one or more repeating units selected from four specific repeating units containing an aromatic group. The layered structure of the present invention provides an electroluminescent device capable of emitting light at a high luminance and a photoelectric conversion device having a high photoelectric conversion efficiency.
