Title:
WAVELENGTH CONVERSION MEMBER, BACKLIGHT UNIT COMPRISING SAME, LIQUID CRYSTAL DISPLAY DEVICE, AND WAVELENGTH CONVERSION MEMBER MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/125479
Kind Code:
A1
Abstract:
[Problem] To provide a wavelength conversion member, a backlight unit, and a wavelength conversion member manufacturing method, the wavelength conversion member comprising a wavelength conversion layer having quantum dots, and exhibiting excellent lightfastness and high brightness durability when incorporated into a liquid crystal display device. And to provide a liquid crystal display device having excellent light fastness and long-term brightness reliability. [Solution] The present invention comprises: a wavelength conversion layer (30) formed by dispersing quantum dots (30A, B) in an organic matrix (30P); an interlayer (12b) provided adjacent to the wavelength conversion layer (30); and a barrier layer (12a) provided adjacent to the interlayer (12b) on the side opposite to the wavelength conversion layer (30), and having silicon nitride and/or silicon oxynitride as the main component. The organic matrix (30P) is formed by curing a curable composition containing at least an alicyclic epoxy compound. The interlayer (12b) includes a chemical structure A, which is obtained by bonding with the silicon nitride and/or silicon oxynitride, and a chemical structure B, which is obtained by bonding with the organic matrix (30P).
