1. A hard coating laminate having an internal bending property and an external bending property comprising:
a supporting substrate layer; and
a hard coating layer formed on the supporting substrate layer,
wherein the hard coating layer has a thickness of 70 to 200 μm and includes a cured product of a resin composition including a siloxane resin and an elastomeric polymer,
wherein the elastomeric polymer is contained in an amount of 20 to 80 parts by weight based on 100 parts by weight of the siloxane resin,
wherein the elastomeric polymer comprises a polycaprolactone polyol having a number average molecular weight (Mn) of 300 or more and 530 or less, and
wherein the siloxane resin comprises a compound represented by the following Chemical Formula 2,
(R1SiO3/2)a(R2SiO3/2)b(O1/2R)c [Chemical Formula 2]
wherein, in the Chemical Formula 2,
R is a hydrogen atom or an alkyl group having 1 to 20 carbon atoms,
R1 is a functional group represented by the following Chemical Formula a,
a repeating unit including the substituent R1 is included in an amount of 70 mol % to 98 mol %, based on the total molar content of the Chemical Formula 2,
R2 is selected from the group consisting of a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 20 carbon atoms, a substituted or unsubstituted alkenyl group having 2 to 20 carbon atoms, a substituted or unsubstituted alkynyl group having 2 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 20 carbon atoms, a substituted or unsubstituted arylalkyl group having 7 to 20 carbon atoms, a substituted or unsubstituted alkylaryl group having 7 to 20 carbon atoms, an epoxy group, a hydrogen atom, an amino group, a mercapto group, an ether group, an ester group, a carbonyl group, a carboxyl group and a sulfone group, and
a/(a+b)≥0.7, where a is a positive number and b and c are each independently 0 or a positive number, with the proviso that b and c are not simultaneously 0;
 wherein in the Chemical Formula a,
Ra is a substituted or unsubstituted alkylene group having 1 to 6 carbon atoms, or —RbORc— where Rb and Rc are each independently a single bond or a substituted or unsubstituted alkylene group having 1 to 6 carbon atoms.
