Abstract: A display apparatus includes a display element layer including a plurality of emission areas each having a length in a direction, an encapsulation layer over the display element layer, and a light-shielding pattern layer over the encapsulation layer, and defining a plurality of holes respectively corresponding to the plurality of emission areas and spaced apart from each other along the direction by a distance along the direction. A distance from the upper surface of the display element layer at the emission area, to the upper surface of the light-shielding pattern layer, along a thickness direction of the display apparatus, is about 2.6 to about 2.8 times the length of the emission area, and the distance between the plurality of holes of the light-shielding pattern layer is about 1.5 to about 1.7 times the length of the emission area.

Abstract: An optical film may include a polarizer configured to linearly polarize a first light to provide a linearly polarized light component. The optical film may further include a first semi-transmissive film overlapping the polarizer, configured to transmit the linearly polarized light component, and configured to reflect a first circularly polarized component of a second light. The first circularly polarized component of the second light may have a first wavelength. The optical film may further include a second semi-transmissive film overlapping the first semi-transmissive film, configured to transmit the linearly polarized light component, and configured to reflect a second circularly polarized component of the second light. The second circularly polarized component of the second light may have a second wavelength that is unequal to the first wavelength.
