Abstract
There is provided a dispersing liquid for a protective film and a manufacturing method thereof. The manufacturing method of a dispersing liquid for forming a protective film of a plasma display panel comprises adding a MgO powder to a mixed liquid of a solvent and a dispersing agent, forming a first liquid by milling a mixed liquid of the solvent and the dispersing agent to which the MgO powder is added, forming a second liquid comprising a coupling agent and milling the first liquid and the second liquid. Therefore, it is possible to improve a discharge characteristic of a protective film and an adhesive force between a protective film and a dielectric layer due to uniform dispersion of additives by comprising a MgO powder and a coupling agent.
