The shear effects to the L_α-L_3 phase transition was investigated in the hyper-swollen lyotropic liquid crystal. We experimentally confirmed that the shear induced L_3 to L_α phase transition takes place, by using the static light scattering under oscillatory shear flow. The dynamic phase diagram was also constructed based on the quantitative measurement of the peak intensity and the peak wave-length of the Bragg reflection. It is emphasized that the phase transition order is modified from the first order to continuous under high shear regime. The fundamental origin of the shear induced phase transition was proposed that the shear flow tears off the passage of the membrane, due to the coupling between the shear flow and the three-dimensional inter-connected structure of the sponge phase.
