[Problem] To provide a liquid dispersion in which an exfoliated layer substance produced by delamination of a layered compound is stable. [Solution] This liquid dispersion contains quaternary ammonium ions (A) having a total of 15-45 carbon atoms and having 1 or 2 alkyl groups having 10-20 carbon atoms, and an anionic surfactant (B) having ammonium ions, wherein plate-shaped particles (C) which has an average thickness of 0.7-40 nm, an average major axis length of 100-600 nm, and an average minor axis length of 50-300 nm, and in which the ratio of the average minor axis length and the average major axis length is 1.0-10.0, are dispersed in a liquid medium, and the plate-shaped particles (C) in the liquid dispersion have an average particle size of 10-600 nm as measured by dynamic light scattering. This transparent substrate uses the liquid dispersion. |
