摘要： The display device substrate according to the present invention is arranged so that: a source line is provided on an area on which a pixel electrode is not provided, and a gap is provided between the source line and the pixel electrode, and a black matrix (light shielding film) which covers a surface of the source line overlaps with the pixel electrode. Thus, it is possible to prevent parasitic capacitance (Csd) between the pixel electrode and the source line from becoming uneven in a display area, so that it is possible to reduce display unevenness of a liquid crystal display device using the present display device substrate.

摘要： An active-matrix substrate includes: scanning signal lines; data signal lines; first storage capacitor wires; second storage capacitor wires; and pixels, disposed at intersections between the scanning signal lines and the data signal lines, each of which includes a plurality of sub-pixels. Each of the data signal lines is split into two parts at a region where the number of scanning signal lines intersecting the data signal line is ½ of the total number of scanning signal lines. A data signal line split section is formed on a region that does not overlap the second storage capacitor wires. This makes it possible to provide an active-matrix substrate, a display device, and a television receiver in each of which a data signal line split into two parts and a storage capacitor wire are hardly electrically short-circuited in the case of a combination of a split-screen structure and a multi-pixel structure.
