Abstract

The present invention addresses the problem of providing a laminate film which is provided with an optical functional layer such as a quantum dot layer, and which is capable of inhibiting deterioration of the optical functional layer due to oxygen or the like. The present invention is provided with: a laminate obtained by laminating a gas barrier layer on at least one of the surfaces of an opticalfunctional layer; and resin layers which cover end surfaces of the laminate, are formed from a composition including, when the total solid content is 100 parts by mass, at least 5 parts by mass of acompound having at least one polymerizable functional group selected from a (meth)acryloyl group, a vinyl group, a glycidyl group, an oxetane group, and an alicyclic epoxy group, and have an oxygen permeability of not more than 10 cc / (m<2>*day*atm).

Description

technical field

[0001] The present invention relates to a laminated film used for backlights of liquid crystal display devices and the like. Background technique

[0002] A liquid crystal display device (hereinafter, also referred to as LCD (Liquid Crystal Display)) is an image display device that consumes less power and saves space, and its use is expanding year by year. Further, in liquid crystal display devices in recent years, further power saving, improvement of color reproducibility, and the like are required to improve LCD performance.

[0003] With the demand for power saving of LCD, it is proposed to use quantum dots (QD (Quantum Dot) which convert the wavelength of incident light and emit light in the backlight in order to improve the light utilization efficiency in the backlight (backlight unit) and improve the color reproducibility. ).

[0004] A quantum dot is a state of electrons whose movement direction is restricted in all three-dimensional directions, and ...
