- Liquid Crystal Display Device and Semiconductor Nanocrystal-Polymer Composite

摘要

A liquid crystal display device and a semiconductor nanocrystal-polymer complex are disclosed. The liquid crystal display device includes an LED light source; A liquid crystal panel; A light conversion layer provided so as to be spaced apart from the LED light source; Wherein the light conversion layer comprises semiconductor nanocrystals and a polymer, Wherein the semiconductor nanocrystals convert light incident from the LEDs into light of a different color, the polymer being selected from the group consisting of polyacrylic acid; Polymethacrylic acid; A polymer containing a carboxyl group (-COOH) or a salt thereof (-COOM, wherein M is a monovalent metal cation); A polymer containing a carboxylate anion group (-COO ^- ) and a metal cation bonded to the carboxylate anion group (wherein the metal cation is a metal cation having a valence of two or more) ) Polymers; And combinations thereof, and a second polymer selected from the group consisting of a polyolefin; Cyclic olefin polymer (COP); Polyacrylic acid; Polymethacrylic acid; A polymer containing a carboxyl group (-COOH) or a salt thereof (-COOM, wherein M is a monovalent metal cation); A modified polymer comprising a polymer containing a carboxylate anion group (-COO ^- ) and a metal cation bonded to the carboxylate anion group (wherein the metal cation means a divalent or higher metal cation); And a second polymer selected from a combination thereof.
