1. A light-emitting display apparatus comprising:
a substrate;
a first insulating layer on the substrate;
a signal wiring on the first insulating layer;
a second insulating layer on the substrate and including a first opening or groove, the second insulating layer being separated by the first opening or groove;
a conductive layer on a top surface of the second insulating layer, the conductive layer directly contacting the first insulating layer inside the first opening or groove;
a light-emitting device on the second insulating layer, the light-emitting device defining an active area and comprising;
a first electrode,
a second electrode disposed on the conductive layer and extending outside the first opening or groove, the second electrode being in direct contact with the conductive layer inside the first opening or groove, and
an intermediate layer between the first and second electrodes;
a third insulating layer covering a part of the first electrode; and
a circuit unit located below the second insulating layer and outside the active area, the circuit unit comprising a plurality of thin-film transistors.
