Abstract

An object of the present invention is to provide a polysiloxane compound that can be developed in an aqueous alkali solution and can yield a cured product or thin film having superior heat-resistant transparency and insulating properties, a curable composition thereof, and a thin film transistor provided with a passivation layer or gate insulator using the same, and the present invention relates to a polysiloxane compound having at least one photopolymerizable functional group in a molecule thereof, and having at least one member selected from the group consisting of an isocyanuric acid backbone structure, a phenolic hydroxyl group and a carboxyl group within the same molecule, to a curable composition containing the polysiloxane compound, and to a cured product thereof.
