a plurality of sub-pixels disposed in an array on the substrate;

a plurality of data lines disposed on the substrate; and

a black matrix disposed on a side, distal to the substrate, of the data lines, wherein an orthographic projection of the black matrix onto the substrate covers the data lines; wherein

the plurality of data lines and the plurality of columns of the sub-pixels are alternately arranged in sequence along a row direction of the array, and each data line is connected to one column of the sub-pixels corresponding to the data line;

each of the sub-pixels is divided into at least two domains along a column direction of the array; and

at a domain boundary position of two adjacent domains, the data line deviates from the column direction of the array and bends toward the row direction of the array to form a corner,

wherein a distance between an outer edge of an orthographic projection of the black matrix covering the corner onto the substrate and an outer edge of an orthographic projection of the corner onto the substrate is greater than a distance between an edge of an orthographic projection of the black matrix covering rest of the data line onto the substrate and a corresponding edge of an orthographic projection of the data line covered by the black matrix onto the substrate;

the outer edge corresponds to an edge where a raised side of the corner is located; and

at the outer edge of the orthographic projection of the corner onto the substrate, a distance between a straight line, where a vertex of the corner is located, along the column direction of the array and a straight line, where a bending point forming the corner is located, along the column direction of the array ranges from 1 to 3 μm, such that a transition difference at the corner of the data line is significantly shortened, and a width of a portion covering the corner of the black matrix is relatively increased.
