Display device
A display device with favorable display quality is provided. A display portion where a plurality of pixels is arranged in a matrix is divided into Region A and Region B, i.e., regions on the upstream side and the downstream side of a scanning direction. A signal line for supplying an image signal is provided in each of Region A and Region B. Region A and Region B adjoin each other such that a boundary line showing the boundary between the regions is bent. Bending the boundary line suppresses formation of a stripe in a boundary portion. For example, in a given column, the total number of pixels electrically connected to a signal line in Region A is made different from the total number of pixels electrically connected to a signal line in Region B.
