Patent ID: 8259246

Claim:
An active matrix substrate comprising: scanning signal lines and retention capacitor lines both extending in a first direction; data signal lines extending in a second direction intersecting with the first direction; and pixel regions in each of which: a corresponding one of the scanning signal lines crosses the pixel region; at least one pixel electrode is provided on one of both sides, extending along a longitudinal direction of the corresponding one of the scanning signal lines, of the corresponding one of the scanning signal lines while at least one pixel electrode is provided on a counter side; and transistors are provided on the corresponding one of the scanning signal lines so as to correspond respectively to the pixel electrodes, wherein: each of the retention capacitor lines has a retention capacitor line extension extending along a corresponding one of the data signal lines from an intersection of this retention capacitor line and the corresponding one of the data signal lines toward each of two intersections of the corresponding one of the data signal lines and two scanning signal lines adjacent to this retention capacitor line; the retention capacitor line extension has a part where the retention capacitor line extension and the corresponding one of the data signal lines overlap each other in planar view; drain drawing lines are provided for electrically connecting drains of the transistors with the pixel electrodes, respectively; the retention capacitor line extension has a sub-extension extending toward a corresponding one of the drain drawing lines; the sub-extension has a part where the sub-extension and the corresponding one of the drain drawing lines overlap each other in planer view; each of the scanning signal lines has openings which positionally correspond respectively to the transistors provided to this scanning signal line, the openings each extending from an inside of a corresponding one of the pixel regions to an outside thereof beyond a corresponding one of the data signal lines; and on at least the one of both sides of each opening, each of the scanning signal lines has a part functioning as a gate electrode of a corresponding one of the transistors.
