Abstract
Provided is an organic light emitting display panel including a transistor layer, first and second insulation film pattern, an anode electrode, an emission unit, and a cathode electrode. The transistor layer is disposed on a substrate. The first insulation film pattern is disposed at each pixel and disposed on an inter-layer insulation film covering the transistor layer. The second insulation film pattern has an area larger than an area of the first insulation film pattern and covers the first insulation film pattern. The anode electrode covers the second insulation film pattern and is provided with an edge having a round-shaped cross section. The emission unit covers the anode electrode and a cathode electrode is disposed on the emission unit.
