1. An organic light-emitting display device comprising:
a light-blocking layer disposed on a substrate;
a buffer layer disposed on the light-blocking layer;
an active layer disposed on the buffer layer;
a first metal layer disposed on the active layer; and
a gate insulating layer disposed on the first metal layer,
wherein a contact-hole is formed in the first metal layer and the gate insulating layer and in an area of overlapping with the light-blocking layer, and
wherein the active layer and the first metal layer extend from the contact-hole to a channel of a thin-film transistor.
