Liquid crystal display panel, and liquid crystal display device

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. An odd-numbered individual driver and an even-numbered individual driver each output a corresponding one of drive signals of opposite polarity. Thus, the polarities of subpixels of the same color arranged in a first direction D(horizontal direction) differ between the subpixels connected to the odd-numbered signal line group and the subpixels connected to the even-numbered signal line group. 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.
