Abstract
An ink composition and a display apparatus including a layer and that is formed using the ink composition. The ink composition includes a scatterer, a monomer, and a dispersant. The layer formed using the ink composition has a refractive index of about 1.1 to about 1.5. A lateral luminance of the display apparatus is improved as a result thereof.
