Organic light emitting display device and method of manufacturing organic light emitting display device

An organic light emitting display device comprising:

• a substrate including a first region and a second region;
• a first transistor, the first transistor including:
• a first active layer having a source region and a drain region disposed in the first region on the substrate,
• a first gate electrode disposed on the first active layer with a gate insulating layer disposed between the first active layer and the first gate electrode,
• a first source electrode disposed on the first gate electrode with a first insulating interlayer disposed between the first gate electrode and the first source electrode, the first source electrode being connected to the source region,
• a sacrificial layer structure disposed to be spaced apart from the first source electrode, the sacrificial layer structure having an opening,
• a protective insulating layer disposed on the first source electrode and the sacrificial layer structure, and
• a first drain electrode disposed on the protective insulating layer, the first drain electrode being connected to the drain region through the opening;
• and
• a sub-pixel structure disposed on the first transistor.

A method of manufacturing an organic light emitting display device, the method comprising:

• preparing a substrate having a light emitting region that includes a first region and a second region, a peripheral region that surrounds the light emitting region, and a bending region that is disposed in one side of the peripheral region;
• forming a first active layer having a source region and a drain region in the first region on the substrate;
• forming a first gate electrode on the first active layer with a gate insulating layer disposed between the first active layer and the first gate electrode;
• forming a sacrificial layer structure overlapping the drain region of the first active layer in a plan view with an insulating interlayer disposed between the first gate electrode and the sacrificial layer;
• forming a protective insulating layer on the sacrificial layer structure;
• forming a first contact hole exposing the drain region, the first contact hole being formed through the sacrificial layer structure;
• forming a first drain electrode connected to the drain region through the second contact hole;
• and
• forming a sub-pixel structure on the first drain electrode.
