QUANTUM DOT SHEET, BACKLIGHT DEVICE, DISPLAY, AND MANUFACTURING METHOD OF QUANTUM DOT SHEET

摘要

PROBLEM TO BE SOLVED: To effectively suppress a barrier film from being peeled off at the ends from a quantum dot layer.SOLUTION: According to an aspect of the present invention, there is provided a quantum dot sheet comprising: a quantum dot layer that includes a light incident surface receiving light and a light emission surface emitting light, and quantum dots and a binder resin converting the wavelength of the light received on the light incident surface; a first barrier film that is adhered to the light incident surface of the quantum dot layer; and a second barrier film that is adhered to the light emission surface of the quantum dot layer, wherein the initial peeling strength of the first barrier film at the ends of the light incident surface of the quantum dot layer, and the initial peeling strength of the second barrier film at the ends of the light emission surface of the quantum dot layer are 2.0 N/25 mm or more in a condition of a rate of pulling of 0.3 m/min.SELECTED DRAWING: Figure 1
