    Abstract: A display apparatus includes a first transistor, a first pixel electrode, a second transistor, and a second pixel electrode. The first transistor includes a first drain electrode. The first pixel electrode is positioned between an edge of the display apparatus and a center of the display apparatus and includes a first recessed structure. The first recessed structure directly contacts the first drain electrode. The second transistor includes a second drain electrode. The second pixel electrode is positioned between the edge of the display apparatus and the first pixel electrode and includes at least one recessed structure. The at least one recessed structure includes a second recessed structure. The second recessed structure directly contacts the second drain electrode. A total maximum width of the at least one recessed structure is greater than a maximum width of the first recessed structure.

The light-shielding layer is disposed on the patterned layer, and includes: second body portions, and a second opening between the second body portions. The first electrode is disposed on the substrate, the first and second openings overlap the first electrode. The second electrode overlaps the first electrode. The EL is disposed between the first and second electrodes. The FIL is disposed on the second electrode. The CF is disposed on the FIL. The EL is at least disposed in the first opening, and the FIL and the CF are at least disposed in the second opening.

    Abstract: A display apparatus includes: a display layer including a plurality of organic light emitting elements, and defining a plurality of light emitting areas and a non-light emitting area surrounding the light emitting areas; and an input sensing layer on the display layer. The input sensing layer includes: a first conductive pattern on the display layer; an insulating layer on the first conductive pattern to cover the first conductive pattern, and defining a plurality of light collecting patterns overlapping with the light emitting areas in a plan view; a second conductive pattern on a top surface of the insulating layer; and an overcoat layer on the second conductive pattern to cover the insulating layer and the second conductive pattern. Each of the light collecting patterns is recessed downward from the top surface of the insulating layer.
