Document Type and Number:
WIPO Patent Application WO/2015/025950
Kind Code:
A1
Abstract:
An aspect of the present invention relates to a light conversion member having a light conversion layer including quantum dots which are excited by incident excitation light and emit fluorescence, wherein the light conversion layer includes quantum dots (A) having a center emission wavelength in a wavelength band in the range of 600-680 nm, and one or more types of quantum dots (Z) having a center emission wavelength in a shorter wavelength band than the quantum dots (A), and in the light conversion layer, the quantum dots (A) are unevenly distributed to the excitation light incidence side relatively with respect to the quantum dots (Z).
