Claim 8:
9. A method for manufacturing a dispersion liquid of carbon nanotubes, the method comprising:
forming an admixture comprising a solvent and carbon nanotubes in a mixing device;
performing a primary dispersion of the carbon nanotubes by rotation of a rotor in a first dispersion device after receiving an inflow of the admixture from the mixing device;
performing a secondary dispersion of the carbon nanotubes by discharging the primarily dispersed carbon nanotubes through a plurality of penetration holes of a stator surrounding the rotor by the rotation of the rotor; and
performing a tertiary dispersion to the secondary dispersed carbon nanotubes by a second dispersion device using laser;
wherein the first dispersion device comprises:
a storage tank connected to the mixing device for receipt of the inflow of the admixture therefrom;
the rotor comprising a rotation shaft disposed in an inner center of the storage tank along an inflow direction of the admixture, and operable to rotate in a direction perpendicular to an inflow direction of the admixture; and
the stator comprising an open side facing the inflow direction of the admixture, a closed side fixed to the storage tank, and the plurality of penetration holes, formed on a circumference surface surrounding the rotor.
