Organic light-emitting display device and manufacturing method thereof

A method of manufacturing an organic light-emitting display device, the method comprising:

• forming a conductive layer;
• forming an insulating layer covering the conductive layer;
• forming a thin film transistor over the conductive layer, the thin film transistor including a semiconductor layer and a gate electrode overlapping the semiconductor layer;
• forming a passivation layer covering the thin film transistor;
• forming a pixel electrode over the passivation layer, the pixel electrode being electrically connected to the thin film transistor via a contact hole defined in the passivation layer;
• forming a pixel-defining layer covering an edge of the pixel electrode;
• forming an emission layer over the pixel electrode;
• forming a hole exposing a portion of the conductive layer;
• and
• forming an opposite electrode, the opposite electrode being electrically connected to the conductive layer via the hole and facing the pixel electrode with the emission layer disposed therebetween.
