A photopolymerizable composition comprising:
- a first monomer having a first photocurable functional group;
- a second monomer having a second photocurable functional group;
- and
- an initiator,
- wherein the first and second monomers satisfy the following Equation 1:
- C
- =
- ❘
- "\[LeftBracketingBar]"
- A

- in Equation 1,
- C is an absolute value (mN/m) of a deviation of surface tension of the second monomer with respect to surface tension of the first monomer;
- A is surface tension (mN/m) of the first monomer at 25° C.;
- and
- B is surface tension (mN/m) of the second monomer at 25° C.
