PROBLEM TO BE SOLVED: To provide a transparent film-forming coating liquid for forming a transparent film having refraction index which decreases gradually from a lower layer to an upper layer, excellent in light transmissivity, transparency, and having antistatic and antireflection performances.SOLUTION: A transparent film-forming coating liquid contains a surface finishing silica-based fine particle (A), surface finishing chain conductive metal oxide particles (B), a matrix forming component and a solvent. The average particle diameter of the surface finishing silica-based fine particle (A), (D) is in the range of 10 to 200 nm. The surface finishing chain conductive metal oxide particles (B) are chain conductive particles in which 2 to 30 metal oxide particles having an average particle diameter (D) in the range of 5 to 20 nm are connected in a chain, where the metal oxide particles have a volume resistivity value in the range of 10to 10&OHgr; cm. The concentration of the surface finishing silica-based fine particle (A) is in the range of 0.05 to 35 wt.% as a solid content, the concentration of the surface finishing chain conductive metal oxide particles (B) is in the range of 0.025 to 25 wt.% as a solid content, the concentration of the matrix forming component is in the range of 0.1 to 42.5 wt.% as a solid content and the total solid content concentration is in the range of 0.5 to 50 wt.%. |
