A pixel array includes scan lines extended along a row direction in a zigzag manner, data lines extended along a column direction, and pixels connected the scan lines and the data lines. Each pixel arranged in nth row includes a first sub-pixel and a second sub-pixel. The first sub-pixel includes a first transistor and a first pixel electrode. A first gate electrode and a first drain electrode of the first transistor are respectively connected to the (n+1)th scan line and the first pixel electrode. A second sub-pixel includes a second transistor and a second pixel electrode. A second gate electrode and a second drain electrode of the second transistor are respectively connected to the nth scan line and the second sub-pixel electrode. A first source electrode of the first transistor and a second source electrode of the second transistor are connected to the same data line.
