A coating liquid including one or more of metal complexes selected from a metal complex A represented by Chemical Formula 1, a metal complex B represented by Chemical Formula 2, and a metal complex C represented by Chemical Formula 3. M in Formula 1, 2 and 3 represents a metal ion. Each of X1-X4 in Formula 1, 2 and 3 is one of O, NH, CO2 and S. Each of Y1-Y8 in Formula 1 and Y1-Y4 in Formula 3 is either CH or N. Each of Z1-Z3 in Formula 2 and 3 and Z4-Z6 in Formula 2 is one selected from a group of O, NH and S, and two selected from a group of CH and N. L represents an axial ligand. k represents a valence of each of the metal complexes and is equal to a sum of electric charges of M, X1-X4 and L.
