CURABLE SILICONE COMPOSITION CAPABLE OF HAVING DOME SHAPE, AND CURED PRODUCT THEREOF
The present invention relates to a curable silicone composition and a cured product thereof. The silicone composition has thixotropicity through surface-modified fumed silica of the curable silicone composition, and thus can be discharged and cured into a dome shape and has excellent transparency and light extraction efficiency. In addition, the silicone composition contains a surfactant so as to improve fluidity, and thus a uniform dome diameter can be implemented when the silicone composition is discharged in a dome shape.
