  • Coating composition for transparent electrode passivation layer and transparent electrode having passivation layer
    Patent number: 9881713
    Abstract: Provided is a coating composition for a transparent electrode passivation layer, the coating composition including a metal oxide and at least one selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol, triethylene glycol, and tetraethylene glycol. When a passivation layer formed using the coating composition for a transparent electrode passivation layer according to the present invention is applied to a transparent electrode, the passivation layer is capable of ensuring the heat resistance and durability of the transparent electrode while maintaining the transmittance of the transparent electrode. Particularly, the coating composition for a transparent electrode passivation layer according to the present invention exhibits excellent hardness.
