We formulate a viscoelastic theory of micro-phase separated structures in diblock copolymers in which the local composition is coupled with the molecular orientation. The linear viscoelastic response is investigated for aligned lamellar structures. Three kinds of complex moduli and viscosities characterizing an incompressible lamellar structure are obtained up to the leading order of the coupling.
