Substrate including thin film transistors and organic light emitting display apparatus including the substrate

摘要

A substrate includes a thin film transistor (TFT) which includes an active layer, a gate electrode, a source electrode, and a drain electrode; a first insulating layer disposed between the active layer and the gate electrode; a second insulating layer disposed between the gate electrode and the source and drain electrodes; a third insulating layer disposed on the second insulating layer, and including a first region for opening the second insulating layer and a second region for opening one of the source and drain electrodes, the first region and the second region being integrally connected; and a first electrode connected to one of the source and drain electrodes, and disposed so as to cover the first region and the second region.

1. A substrate, comprising:
a thin film transistor (TFT) including an active layer, a gate electrode, a source electrode, and a drain electrode; a first insulating layer disposed between the active layer and the gate electrode; a second insulating layer disposed between the gate electrode and the source and drain electrodes; a third insulating layer disposed on the second insulating layer, and including an integrally formed hole which exposes the second insulating layer in a first region and which exposes one of the source and drain electrodes in a second region; and a first electrode connected to one of the source and drain electrodes, disposed to cover the first region and the second region, and directly contacting the second insulating layer exposed by the integrally formed hole in the first region, a portion of the third insulating layer interposed between the first electrode and the second insulating layer.
