Organic light-emitting display apparatus

摘要

An organic light-emitting display apparatus includes a thin film transistor including an active layer, a gate electrode, source and drain electrodes, a first insulating layer between the active layer and the gate electrode, and a second insulating layer between the gate electrode and the source and drain electrodes, a third insulating layer covering the source and drain electrodes, the third insulating layer being an organic insulating layer, a pixel electrode including a semi-transparent metal layer and having an end located in a trench formed around the first insulating layer, a fourth insulating layer including an opening exposing a top surface of the pixel electrode, the fourth insulating layer being an organic insulating layer, an organic light-emitting layer on the pixel electrode, and a counter electrode on the organic light-emitting layer.
