## Abstract

A display panel includes a first pixel group including sub-pixels coupled to a first scan line and located in first through N-th sub-pixel columns, where N is an even number greater than or equal to 2, a second pixel group including sub-pixels coupled to the first scan line and located in (N+1)-th through 2N-th sub-pixel columns, a third pixel group including sub-pixels coupled to a second scan line adjacent to the first scan line and located in the first through N-th sub-pixel columns, and a fourth pixel group including sub-pixels coupled to the second scan line and located in the (N+1)-th through 2N-th sub-pixel columns. The first pixel group and the second pixel group are driven during a first scan on time in which the first scan line is driven. Consecutive N−1 sub-pixels among the sub-pixels of the third pixel group and one sub-pixel among the sub-pixels of the fourth pixel group are driven during a first portion of a second scan on time in which the second scan line is driven, and consecutive N−1 sub-pixels among the sub-pixels of the fourth pixel group and one sub-pixel among the sub-pixels of the third pixel group are driven during a second portion of the second scan on time.
