Abstract
A composition for fabricating an organic film, an organic light-emitting display apparatus manufactured using the same, and a method of manufacturing the organic light-emitting display apparatus, the composition comprising a first compound that includes n substituents Y, and m polymerizable groups P1, wherein n is selected from 1, 2, 3, and 4; m is selected from 1, 2, 3, and 4; OP1 of the first compound is equal to or greater than 2.8 and equal to or less than 4.8; OP1 being (total number of atoms of the first compound)/{(number of carbon atoms of the first compound)−(number of oxygen atoms of the first compound)}; and RP1 of the first compound is equal to or greater than 0.01 and equal to or less than 0.46; RP1 being {(number of carbon atoms of the substituent Y)X n}/(number of carbon atoms of the first compound).
