We studied the mixture of the thermotropic and lyotropic liquid crystals. We have found for the first time the trasparent nematic phase where nematic director is locally distorted by the randomly dispersed inverse micelles. Thus, system has isotropic nature, nevertheless nematic order is completely accomplished. We also success to explain physical mechanism of the phase behavior of this system by the thermodynamic discussion using the explicit formula of the free energy density including the distortion of nematic director. Calculated phase diagram is much consistent with experimental results. Nematic order parameter fluctuation above the weak first-odrder isotropic-nematic phase transition is strongly suppressed by introducing the inverse miceltes.
