1. A liquid crystal display panel comprising:
a plurality of scanning lines, wherein the plurality of scanning lines are disposed along a first direction and extend along a second direction;
a plurality of data lines, wherein the plurality of data lines are disposed along the second direction and extend along the first direction, and the second direction intersects the first direction; and
a plurality of sub pixels, wherein: the plurality of sub pixels are disposed in an array, and colors of the sub pixels in each column are same; polarities of the sub pixels in each column are changed every k rows, and k is an integer greater than or equal to 1; and polarities of two adjacent ones of the sub pixels in each row are opposite,
wherein: along the second direction, the sub pixels in an nth column are correspondingly connected to two adjacent ones of the data lines located at a left side and a right side of the sub pixels in the nth column; one of the two adjacent ones of the data lines is electrically connected to positive sub pixels of the sub pixels in the nth column, and another one of the two adjacent ones of the data lines is electrically connected to negative sub pixels of the sub pixels in the nth column; every two of the data lines transmitting data voltages with same polarities and electrically connected to the sub pixels of a same color are connected together; n is an integer greater than or equal to 1; and a (2m)th data line is electrically connected to a (2m+17)th data line along the second direction, and m is an integer greater than or equal to 1.
