Abstract:
1. An organic light emitting display panel comprising: a base substrate comprising a plurality of light emitting areas and a non-light emitting area surrounding the light emitting areas; a first electrode disposed in a first light emitting area of the plurality of light emitting areas; a second electrode disposed in a second light emitting area of the plurality of light emitting areas, wherein the second light emitting area is adjacent to the first light emitting area; a hole injection layer contacting the first electrode and the second electrode, and disposed to overlap with the first and second light emitting areas and the non-light emitting area; a first hole transport layer disposed over the hole injection layer disposed in the first light emitting area; a first light emitting layer disposed on the first hole transport layer contacting the first hole transport layer; a second hole transport layer disposed over the hole injection layer disposed in the second light emitting area; a second light emitting layer disposed on the second hole transport layer contacting the second hole transport layer; and a common electrode disposed on the first light emitting layer and the second light emitting layer to overlap with the plurality of light emitting areas and the non-light emitting area, wherein a portion of the first hole transport layer and a portion of the second hole transport layer are overlapped and wherein a portion of the first hole transport layer and a portion of the first light emitting layer are disposed over the hole injection layer in the second light emitting area.
