Specifically, in this embodiment, the difference between the block resistance of the first scan line 122a (the second scan line 122b) and the block resistance of the second bridge line 152 is less than or equal to 0.1Ω. The difference between the block resistance of the first data line 142a (the second data line 142b) and the block resistance of the first bridge line 132 is less than or equal to 0.05Ω.

In this embodiment, the block resistance of the second bridge line 152 bridged with the first scan line 122a is same as or similar to the block resistance of the first scan line 122a. And, the block resistance of the first bridge line 132 bridged with the first data line 142a is same as or similar to the block resistance of the first data line 142a. Therefore, the problem of abnormal display due to difference in resistance between different metal layers when bridging the different metal layers can be solved, thereby improving screen display effect.

In addition, in this embodiment, a water-oxygen blocking layer is further provided around the blind/through hole 19, which can effectively enhance durability and reliability of the display panel.
