FIG. 3 is a cross-sectional view of the display apparatus of FIG. 1 taken along line A-A′ of FIG. 1 and line B-B′ of FIG. 2, according to an exemplary embodiment. FIG. 4 is a cross-sectional view of the display apparatus of FIG. 1 taken along lines B-B′ and C-C′ of FIG. 2, according to an exemplary embodiment. FIG. 5 is a conceptual diagram illustrating the portion D of FIG. 1, according to an exemplary embodiment.

FIGS. 3 and 4 are cross-sectional views of portions that are spaced apart from each other in FIG. 1 and are not adjacent to each other. FIG. 3 illustrates a pixel PX1 and a pixel PX2. As illustrated in FIG. 3, the pixel PX1 and the pixel PX2 may not be adjacent pixels. Also, FIG. 3 is the cross-sectional view of the portions that are spaced apart from each other in FIG. 1. In an exemplary embodiment, cross-sections of the portions that are spaced apart from each other are not in the same direction. That is, for convenience of illustration, line A-A′ of FIG. 1 is shown as a straight line, however, in exemplary embodiments, line A-A′ may be a curved line or a may be bent a plurality of times. In any case, it is understood that FIG. 3 is the cross-sectional view illustrating portions of the pixel PX1 and the pixel PX2 in the display area DA and a portion of the peripheral area PA.
