Cardo system adhesive resin of the invention can make relative to the solid component total amount in light conversion resin combination
With 40~99 weight %, 50~98 weight % preferably can be used.If the content of adhesive resin is within the above range, apply
The formation of coating and the protection feature of quantum dot well are easy to improve the characteristics of luminescence and reliability, but are less than the feelings of above range
Under condition, it may occur however that the problem of reliability of overlay reduces, in the case where above, it may occur however that the characteristics of luminescence is insufficient
Problem.
In addition, the present invention can be using cardo system adhesive resin as neccessary composition, and further include acrylic acid tree
Rouge.At this moment, cardo system adhesive resin uses 10 parts by weight~800 parts by weight relative to acrylic resin, more preferably uses 15
~600 parts by weight, this plays more effective characteristic for improving heat resistance and light emission luminance.
The case where in the case that cardo system adhesive resin is less than above range, light emission luminance is reduced, and is more than above range
Under, cause the reduction of heat resistance.
