A matrix-type display device having a repair layout, particularly, a matrix-type display device which can be repaired in a pixel unit, is provided. Two or more of signal lines such as scanning signal lines, displaying signal lines and auxiliary signal lines and a pixel electrode are overlapped via an insulating layer, so that a defect such as the disconnection of the displaying signal lines and scanning signal lines, the short of the pixel electrode and signal line, and the loss of electrode of a switching element, can be repaired Here, the layout of the auxiliary gate line and dual gate line can be modified.
