The minimum width of the bezel area 102 at any position is the narrowest width that can be achieved by processes in a case where the peripheral circuit and the peripheral signal lines are fully laid at that position.

In some implementations, the total distribution widths, at arbitrary positions, of the shift register circuit 4 and the first signal line distributed in the second sub-part 1052 being the same does not only mean that the total distribution widths are absolutely the same, but also includes a case that the total distribution widths are approximately the same within a certain error range. That is, the total widths of the area, occupied by a distribution of the shift register circuit 4 and the first signal line, at arbitrary positions in the second sub-part 1052 may be absolutely equal or may be approximately equal within a certain error range, and the total distribution width may include a certain measurement error (i.e., a difference caused by the certain measurement error may exist between the total widths), for example, the measurement error is about 0.3 μm.

In some implementations, the distribution width of the data line 5 (i.e., a width of an area in which the data line 5 is distributed, or a width of an area occupied by the data line 5) in the second part 106 gradually increases from an end of the second part 106 close to the first part 105 to an end of the second part 106 close to the third part 107.
