Abstract: A black matrix of the display panel comprises N columns of first sub-regions and M columns of second sub-regions, the pixel electrodes comprise N columns of first pixel electrodes in one-to-one correspondence with N columns of first sub-regions and M columns of second pixel electrodes in one-to-one correspondence with M columns of second sub-regions. A width of the M columns of second sub-regions and a width of the M columns of second pixel electrodes along the row direction of the black matrix are increased only by reducing a width of the N columns of first sub-regions along the row direction of the black matrix, such that some signal lines in the divided gate driver may be placed at the M columns of second sub-regions to enable the display panel not having frames at the left and the right, without substantially not changing the aperture ratio of the display panel.
