Abstract:
1. A photo-mask for manufacturing a thin-film transistor substrate, the photo-mask comprising a first exposure area, a second exposure area and a third exposure area, the second exposure area located between the first exposure area and the third exposure area, the photo-mask comprising: a first peripheral line pattern located in the first exposure area; a first dummy line pattern located in the first exposure area and connected to the first peripheral line pattern; a first overlapping pixel pattern located in the first exposure area and connected to the first dummy line pattern; and a second overlapping pixel pattern located in the second exposure area, the first overlapping pixel pattern being complementary to the second overlapping pixel pattern, wherein two patterns respectively formed from exposing through the first exposure area and the second exposure area are unified after exposing through and overlapping the first overlapping pixel pattern and the second pixel pattern are exposed.
