In an active matrix type display device having a drive circuit at one side of an active matrix substrate and feeding a common voltage V com to a counter substrate side via a common transfer, the area of a frame region is reduced without degrading the yield. A pixel region (12) of the active matrix substrate (10) includes (a) an actual pixel region containing an effective pixel for performing a display in accordance with a data signal supplied by signal lines, and (b) a dummy pixel region positioned at the panel end side as compared to the actual pixel region. At least a part of a common wiring (14) is arranged in the dummy pixel region of the pixel region, for supplying a common signal to common transfers (15a, 15b) arranged on a side facing the side of the active matrix substrate (10) where a bus line drive circuit (16) is arranged.
