Display substrate and organic light emitting display device including the same

An organic light emitting display device, comprising:

• a display substrate, comprising:
• an active pattern comprising an active line extending along a first direction;
• a signal line comprising an initialization voltage line partially overlapping the active line with a gate insulation layer in between, a gate line and an initialization line extending along the first direction, and a data line and a power line extending along a second direction intersecting the first direction;
• and
• a plurality of pixels each connected to the signal line, the plurality of pixels each comprising a plurality of thin film transistors formed along the active pattern, a capacitor connected to the power line, and an organic light emitting diode,
• wherein the initialization voltage line partially overlapping the active line with a first insulation layer in between includes:
• a first substantially linear portion and a second substantially linear portion separate from the first substantially linear portion, each of which extends extending-along the first direction;
• and
• an angled portion disposed between and connecting the first substantially linear portion and the second substantially linear portion, the angled portion having at least one side surface extending along a third direction different from and intersecting the first and second directions;
• wherein each of the active and initialization voltage lines has side surfaces, and a first horizontal distance between a side surface of the active line and a side surface of the first substantially linear portion of the initialization voltage line is greater than about 0.45 μm.
