1. A display panel, comprising:
a first display region and a second display region adjacent to the first display region, the second display region divided into at least one transmission cell;
a plurality of first pixels in the first display region, each of the plurality of first pixels including at least one transistor and a light-emitting element connected to the at least one transistor; and
a plurality of second pixels in the second display region, the plurality of second pixels including a plurality of light-emitting pixels and a plurality of non-light-emitting pixels, the plurality of light-emitting pixels providing colors substantially the same as colors produced from the plurality of first pixels, the plurality of non-light-emitting pixels being defined by absence of at least one of the transistor or the light-emitting element,
wherein the at least one transmission cell is defined by multiplication of a number of row pixels arranged in a first direction among the plurality of second pixels and a number of column pixels arranged in a second direction among the plurality of second pixels, the second direction intersecting the first direction, the at least one transmission cell including a contiguous group of the plurality of non-light-emitting pixels,
wherein, in the transmission cell, the plurality of light-emitting pixels bounds the contiguous group of the plurality of non-light-emitting pixels and has different numbers of pixels along the first direction and the second direction,
wherein, in the transmission cell, each of the contiguous group of the plurality of non-light-emitting pixels is bounded on at least two sides by adjacent others of the contiguous group of the plurality of non-light-emitting pixels and bounded on no more than two sides by adjacent ones of the plurality of light-emitting pixels,
wherein, in the transmission cell, the contiguous group of the plurality of non-light-emitting pixels is disposed closer to the center of the transmission cell than the adjacent ones of the plurality of light-emitting pixels.
