Abstract: The encapsulating composition according to the present invention comprises a radical-curable compound having at least one or more radical-curable functional groups, and has composition polarizability of 1.8 or less, wherein the composition polarizability is the sum of values obtained by multiplying each “compound polarizability of radical-curable compounds” constituting the encapsulating composition and “the weight ratio of the relevant radical-curable compound to the encapsulating composition” and the compound polarizability may be calculated by the following general equation 1.


Compound polarizability=(the value obtained by combining the number of carbons and the number of oxygens included in the molecular structure of the relevant radical-curable compound)/(the value obtained by subtracting the number of oxygens from the number of carbons in the molecular structure of the relevant radical-curable compound)  [General Equation 1]
