Abstract
A scanning signal line (16) includes an opening (29) leading from the outside of a pixel region through below a data signal line (15) into the pixel region, and first and second scanning electrode portions (16a/16b) or two side portions of the opening confronting in a column direction through that opening. The end portion of the first scanning electrode portion (16a) in the pixel region is a first end portion (EP1), and the end portion of the second scanning electrode portion (16b) in the pixel region is a second end portion (EP2). A first transistor has a source electrode (9a) and a drain electrode (8a) individually overlapping the first electrode portion (16a) but not the first end portion (EP1) in the pixel region. A second transistor has a source electrode (9b) and a drain electrode (8b) individually overlapping the second electrode portion (16b) but not the second end portion EP2) in the pixel region. According to the aforementioned constitution, it is possible to realize a pixel split type active matrix substrate capable of easily correcting the short-circuits of the data signal line (15) and the scanning signal line (16).
