Display substrate and display device

A display substrate comprising:

• a substrate including a display area and a non-display area surrounding the display area;
• a first insulator disposed over the substrate to straddle the display area and the non-display area, the first insulator including a first film forming area defining recess and at least one second film forming area defining recess recessed from a section of a surface of the first insulator in the non-display area, the first film forming area defining recess and the at least one second film forming area defining recess extending in a first direction;
• a line disposed on the first insulator to extend in a second direction perpendicular to the first direction to straddle the display area and the non-display area;
• a second insulator disposed over the first insulator and the line to straddle the display area and the non-display area, the second insulator having a thickness smaller than a thickness of the first insulator;
• and
• an alignment film disposed over the second insulator at least in the display area, wherein
• the first film forming area defining recess includes a first short edge adjacent to a first side edge of the line,
• the at least one second film forming area defining recess includes a second short edge adjacent to a second side edge of the line on an opposite side from the first side edge so that the line does not cross the first film forming area defining recess and the at least one second film forming area defining recess,
• the first side edge of the line and the first short edge of the first film forming area defining recess are separated from each other,
• the second side edge of the line and the second short edge of the at least one second film forming area defining recess are separated from each other,
• the first insulator includes a first line adjacent section between the first side edge of the line and the first short edge of the first film forming area defining recess,
• the first insulator includes a second line adjacent section between the second side edge of the line and the second short edge of the at least one second film forming area defining recess, and
• the second insulator includes the at least one second film forming area defining recess, and
• the at least one second film forming area defining recess includes second film forming area defining recesses in sections of the second insulator overlapping the line, the first line adjacent section, and the second line adjacent section.
