Abstract

A display device includes: a first pixel group including first, second and third pixels arranged adjacent to each other and positioned successively along a first direction; and a second pixel group including fourth, fifth and sixth pixels arranged adjacent to the first pixel group and positioned successively along the first direction. Multiple ones of each of the first pixel group and the second pixel group are arranged in an alternating manner along both the first direction and a second direction intersecting the first direction. The second pixel and the fifth pixel face each other with respect to a first gate line while being connected to the first gate line, the first pixel and the fourth pixel face each other with respect to a second gate line while being connected to the second gate line.
