Abstract: A display device includes a first substrate on which gate lines and data lines are disposed; a second substrate facing the first substrate; a pixel disposed between the first substrate and the second substrate, and connected to the gate line and the data line; a light blocking layer disposed between the first substrate and the second substrate, and defining a light emission area of the pixel; a polarizer on the second substrate; and a first pattern layer disposed on the polarizer, and comprising a plurality of first protruding portions. The number of first protruding portions that overlap the light emission area among the plurality of first protruding portions is in a range from 3 to 15. An angle between the data line and each of the plurality of first protruding portions is in a range from about 5 degrees to about 10 degrees.

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.

Abstract: A display apparatus includes a display panel, a cover window above the display panel, and an adhesive layer between the display panel and the cover window. The adhesive layer includes: (meth)acrylate having an alicyclic group, (meth)acrylate having a glass transition temperature of about 40° C. or less, cross-linkable (meth)acrylate, and a thermal curing agent including an isocyanate-based compound. The adhesive composition has a first elastic modulus at a first temperature and a second elastic modulus at a second temperature greater than the first temperature, and the second elastic modulus is equal to or greater than the first elastic modulus.
