Abstract

A display apparatus includes gate lines extending in a first direction, data lines extending in a second direction crossing the first direction, and pixels connected to the gate lines and the data lines. The pixels include pixels arranged in a k-th column between a k-th data line and a (k+1)th data line. The pixels arranged in the k-th column are arranged in a plurality of groups, and each of the groups includes 2i first pixels connected to the k-th data line and 2i second pixels connected to the (k+1)th data line. Successive ones of the pixels in each group are connected to the k-th data line and the (k+1)th data line in alternating manner.
