US Patent 11762253 Active matrix substrate and display device

An active matrix substrate includes first lines, a second line, third lines, a first connection electrode, and a second connection electrode. The first lines extend along a first direction and are arranged in a second direction and are portions of a first conductive film. The second line extends along the second direction and cross the first lines and is a portion of a second conductive film. The third lines extend along the second direction and overlap the second line and sandwich one first line and are portions of the first conductive film that differ from the portions configured as the first lines. The first connection electrode crosses the one first line and a second insulating film and is connected to the third lines sandwiching the one first line. The second connection electrode crosses another first line and is connected to the second line and one of the third lines.
