Claim:
1. A composition for forming a hard coating layer, comprising: a first silsesquioxane resin and a second silsesquioxane resin, which have a weight average molecular weight of 500 or more but less than 30,000 and are substituted with a substituent of a (meth)acrylate group, a vinyl group or an epoxy group, the substituent having an equivalent ratio of 50% or more, wherein a hydrodynamic radius ratio of the first silsesquioxane resin to the second silsesquioxane resin is from 1.01 to 2.90, and wherein the first and second silsesquioxane resins are included at a weight ratio in a range of from 1:9 to 9:1, and wherein the first and second silsesquioxane resins are selected from the group consisting of complete-cage type resins, incomplete-cage type resins, ladder type resins, random type resins and mixtures thereof, provided that the first and second silsesquioxane resins are not both complete-cage type resins.
