1. A display panel comprising:
a first pixel area, a second pixel area, and a boundary pixel area disposed between the first pixel area and the second pixel area,
wherein the boundary pixel area includes:
a plurality of first emission regions disposed on at least two row lines and at least two column lines; and
a plurality of second emission regions disposed on the at least two row lines and the at least two column lines,
wherein the plurality of first emission regions are spaced apart from each other in each column line and each row line,
wherein the plurality of second emission regions are connected to each other in a row direction and a column direction between the plurality of first emission regions, and
wherein each of the plurality of first emission regions and the plurality of second emission regions includes one or more pixels,
the second pixel area includes a plurality of emission regions,
at least one of the second emission regions from the plurality of second emission regions is disposed between a pair of first emission regions from said plurality of first emission regions without another one of said plurality of first emission regions between the pair of first emission regions,
a maximum luminance of a first emission region decreases as a distance from the second pixel area increases, and a maximum luminance of a second emission region from said plurality of emission regions increases as a distance from the second pixel area increases,
wherein the plurality of first emission regions and the plurality of second emission regions of the boundary pixel area, and the plurality of emission regions of the second pixel area are arranged into a plurality of lines of emission regions including a first line of emission regions and a second line of emission regions that is disposed directly after the first line of emission regions among said plurality of lines of emission regions, each of the plurality of lines of emission regions including a corresponding first emission region from the plurality of first emission regions at a first side of a boundary between the boundary pixel area and the second pixel area and a corresponding emission region from the plurality of emission regions at a second side of the boundary, and
wherein a first separation distance between outermost pixels that are closest to the boundary amongst all pixels in the corresponding first emission region of the boundary pixel area in the first line of emission regions and outermost pixels that are closest to the boundary amongst all pixels in the corresponding emission region of the second pixel area in the first line of emission regions is a same as a second separation distance between outermost pixels that are closest to the boundary amongst all pixels in the corresponding first emission region of the boundary pixel area in the second line of emission regions and outermost pixels that are closest to the boundary amongst all pixels in the corresponding emission region of the second pixel area in the second line of emission regions,
wherein the first separation distance and the second separation distance is greater than zero.
