Abstract: A display apparatus including a display panel having a display surface on which an image is displayed, and a light condensing member disposed on an upper portion of the display surface. The light condensing member includes a lower condensing layer having a plurality of protrusions protruding upward, and an upper condensing layer having a higher refractive index than the lower condensing layer and disposed on an upper portion of the lower condensing layer to cover the top surface of the lower condensing layer. The protrusions include an upper surface having a planar shape, and a side surface extending downward from an edge of the upper surface and having a curved shape.
