Abstract

A photosensitive resin composition includes (A) a photo-conversion material; (B) a metal-containing compound; (C) a photopolymerizable monomer; (D) a photopolymerization initiator; and (E) a solvent, wherein the metal-containing compound includes a *—S-M-S—* (M is Zn, Al, Mg, Ca, Sc, Ti, 5 V, Cr, Mn, Fe, Co, Ni, Cu, Ga, Sr, Y, Zr, Nb, Mo, Cd, In, Ba, Au, Hg, or Tl) structure, a complex including a polymer matrix in which a photo-conversion material is dispersed, wherein the polymer matrix includes a *—S-M-S—* (M is Zn, Al, Mg, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Ga, Sr, Y, Zr, Nb, Mo, Cd, In, Ba, Au, Hg, or Tl) structure and an ester linking group, a laminated structure including the complex, and a display device and an electronic device including the laminated structure.

First claim

What is claimed is:

1. A complex comprising
a polymer matrix; and
a photo-conversion material dispersed in the polymer matrix,
wherein the polymer matrix is manufactured by polymerizing a photosensitive resin composition comprising a photopolymerizable monomer and a metal-containing compound represented by *—S-M-S—* wherein M is Zn, Al, Mg, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Ga, Sr, Y, Zr, Nb, Mo, Cd, In, Ba, Au, Hg, or Tl, and wherein the polymer matrix comprises an ester linking group.

2. The complex of claim 1 , wherein the metal-containing compound has a weight average molecular weight of greater than or equal to about 1,000 grams per mole and less than or equal to about 15,000 grams per mole.

3. The complex of claim 1 , wherein the photo-conversion material is passivated by the metal-containing compound represented by *—S-M-S—*.

4. A laminated structure, comprising
a substrate; and
a photo-conversion layer disposed on the substrate,
wherein the photo-conversion layer comprises at least one repetitive section emitting light in a predetermined wavelength, and the repetitive section comprises the complex of claim 1 .

5. A display device, comprising
the laminated structure of claim 4 ; and
a light source configured to supply the laminated structure with incident light.

6. A display device, comprising
a backlight unit comprising a light source; and
a liquid crystal panel disposed on the backlight unit,
wherein the liquid crystal panel comprises
a lower substrate,
a photo-conversion layer,
an upper substrate upon which the photo-conversion layer is disposed, and
a liquid crystal layer disposed between the upper substrate and the lower substrate,

wherein the photo-conversion layer faces the liquid crystal layer, and
wherein the photo-conversion layer comprises the complex of claim 1 .

7. The display device of claim 6 , wherein the display device further comprises a polarizer under the liquid crystal panel.

8. The display device of claim 6 , wherein the display device further comprises a polarizer between the liquid crystal layer and the photo-conversion layer.

9. The display device of claim 5 , wherein the light source is an organic light emitting diode.

10. An electronic device, comprising the laminated structure of claim 4 .

11. The electronic device of claim 10 , wherein the electronic device includes a display device, an organic light emitting diode, and a sensor.
