The pixels are located at a display area of the display panel. The first lines are located on a first side of the display area and receive first data signals. The second lines are located on a second side of the display area and receive second data signals. The second side is opposite to the first side. The data lines are electrically connected to the corresponding pixels, respectively. Each of the (4i+1)th and (4i+2)th data lines is electrically connected to one of the (2i+1)th and (2i+2)th first lines exclusively, and each of the (4i+3)th and (4i+4)th data lines is electrically connected to one of the (2i+1)th and (2i+2)th second lines exclusively, wherein i is an integer greater than or equal to 0.
