Abstract: In one embodiment of the present invention, in an even-numbered signal line group, the arrangement sequence of the first and second signal lines is reversed between in a display area and in a non-display area, and the same goes for the arrangement sequence of the third and fourth signal lines. The ends of the first to sixteenth signal lines in the non-display area are connected to the first to sixteenth individual drivers, respectively.

That is, all of the subpixels having the same color arranged in the horizontal direction do not have the same polarity. This helps reduce a horizontal shadow.
