Implementations of the disclosure describe a display apparatus including a backlight unit including a light guide plate, a backlight sheet having a sheet hole formed therein, and a backlight light source element configured to emit light to the light guide plate, a liquid crystal panel positioned on a front surface of the backlight unit, and an optical module positioned on a portion of a back surface of the backlight unit, the portion overlapping the sheet hole. The optical module includes a prism structure including a first prism surface oriented toward the liquid crystal panel, a second prism surface perpendicular to the first prism surface, and an inclined surface provided between the first prism surface and the second prism surface, an optical element positioned adjacent to the second prism surface, and a compensation plate positioned between the first prism surface and the sheet hole, the compensation plate having a light extraction pattern.

A display apparatus comprising: a substrate including a display area in which a plurality of pixels are arranged and a non-display area around the display area, each of the plurality of pixels having a plurality of subpixels; a cathode electrode on the substrate, the cathode electrode disposed in the display area and in a part of the non-display area; an organic layer under the cathode electrode in the display area and in a portion of the non-display area; an organic layer shielding portion in the non-display area, wherein the organic layer is disposed in the portion of the non-display area without being disposed in the organic layer shielding portion; and a low-reflection structure overlapping at least a part of the organic layer shielding portion, the low-reflection structure between the cathode electrode and the substrate in the non-display area.
