Abstract

A display device that is suitable for increasing in size is achieved. Three or more source lines are provided for each pixel column. Video signals having the same polarity are input to adjacent source lines during one frame period. Dot inversion driving is used to reduce a flicker, crosstalk, or the like.

Claims (41)

a fourth pixel, a fifth pixel, and a sixth pixel arranged in a second column,

wherein the first pixel and the fourth pixel are electrically connected to the first gate line,

wherein the second pixel and the fifth pixel are electrically connected to the second gate line,

wherein the third pixel and the sixth pixel are electrically connected to the third gate line,

wherein the second pixel is provided adjacent to the first pixel and the third pixel and adjacent to the fifth pixel,

wherein the first source line, the second source line, and the third source line are provided between the first column and the second column,

wherein the first source line is electrically connected to the first pixel,

wherein the second source line is electrically connected to the third pixel,

wherein the third source line is electrically connected to the fifth pixel,
