Claim:
1. An organic light emitting display device comprising: a substrate having a display region and a transparent region; a first insulating layer disposed on the substrate; an extension of a drain electrode disposed on the first insulating layer, the extension of the drain electrode constituting a semiconductor element in conjunction with an active pattern, a gate electrode, and a source electrode; a second insulating layer disposed on the extension of the drain electrode such that an edge portion of the extension of the drain electrode is free from overlap with the second insulating layer, the side edge portion of the extension of the drain electrode extending in a direction from the display region into the transparent region; a first electrode disposed on the second insulating layer and in contact with the edge portion of the extension of the drain electrode; an emission layer disposed on the first electrode; and a second electrode disposed on the emission layer, wherein at least a portion of the first electrode is in direct contact with the first insulating layer, and wherein the first electrode covers the side edge portion of the extension of the drain electrode such that the side edge portion of the extension of the drain electrode is not exposed in a cross-sectional view of the organic light emitting display device.
