The invention aims at providing A light-shielding paste which contains a thermoplastic resin and an inorganic member as essential components; A light-shielding paste which contains a thermosetting resin and an inorganic member as essential components; A curable composition which contains, as essential components, (A) an organic compound comprising an organic main chain containing at least two carbon-carbon double bonds reactive with a SiH group in each molecule, (B) a silicon compound having at least two SiH groups in each molecule, (C) a hydrosilylation catalyst, (D) a silane coupling agent and/or an epoxy group-containing compound, (E) a silanol condensation catalyst, and (F) an inorganic member; The above curable composition which further contains (G) silica; The above curable composition which shows such a flow leveling property that when the composition is allowed to stand on a glass substrate inclined at an angle of 80 degrees at 100° C. for 1 hour, the flow-out distance is not longer than 2 cm; A light-shielding paste which comprises the above curable composition; or, A method of forming a light-shielding resin layer on a LED package having an aperture comprising a bottom and sidewalls and formed of a molding resin by a monolithic process with the respective ends of an external positive electrode and an external negative electrode being exposed at a predetermined distance on the aperture bottom which method comprises (1) applying a light-shielding paste to a substrate; (2) bringing the LED package aperture into close contact therewith; and (3) heating the LED package with the aperture facing upward; and thereby the light-shielding paste is allowed to spread along the package sidewalls alone. The curable composition of the invention is excellent in light-shielding ability and is highly resistant to light and, therefore, can be used as a light-shielding paste. Further, the curable composition of the invention is low in fluidity and, therefore, light-emitting diodes with the curing product formed on the LED package sidewalls alone can be obtained by using that curable composition. Furthermore, according to the method of light-shielding resin layer formation according to the invention, it is possible to efficiently apply a light-shielding paste to the LED package sidewalls alone for light-shielding resin layer formation, whereby the productivity is markedly improved.
