WAVELENGTH CONVERSION MEMBER BACKLIGHT UNIT INCLUDING WAVELENGTH CONVERSION MEMBER LIQUID CRYSTAL DISPLAY DEVICE AND METHOD OF MANUFACTURING WAVELENGTH CONVERSION MEMBER

摘要

Provided are a wavelength conversion member excellent in oxygen barrier property and reduced in occurrence of bubbles and a method of manufacturing the same, a backlight unit provided with a wavelength conversion member, and a liquid crystal display device. A quantum dot 31 which is disposed between the first base material 10 and the second base material 20 and is excited by the excitation light and emits fluorescence is disposed between the first base material 10 and the second base material 20, The wavelength conversion member 1 having the wavelength conversion layer 30 including the quantum dot 31 and the wavelength conversion layer 30 including the quantum dot 31 and the polymerizable compound having a molecular weight of 200 or less is a cured layer , And the number of bubble-like defects having a diameter of 0.1 mm or more in the wavelength conversion layer 30 is less than 10/100 cm ² .
