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.

Abstract: An adhesive composition is disclosed that includes styrene, polybutadiene, sulfurous ester, isopropenyl toluene, and methylphenylacetylene. A cured product of the adhesive composition has a relative permittivity of at least about 2.0 but not more than about 2.5 wt %. Using the adhesive composition as an antenna film adhesive layer between a display panel and an antenna film or between a functional layer and the antenna film may provide a small thickness of the adhesive layer and improved reliability of a touch sensor and an antenna.
