Abstract:
1. An organic electroluminescent display device, comprising: a thin film transistor formed on an insulating substrate and having a source electrode and a drain electrode; a first insulating layer formed on the insulating substrate having the thin film transistor and having at least one contact hole for exposing one of the source electrode and the drain electrode disposed below the first insulating layer; a reflective film formed on the first insulating layer; a power supply line formed on the first insulating layer and electrically connected to one of the source electrode and the drain electrode through the at least one contact hole; a second insulating layer formed on the insulating substrate having the reflective film and the power supply line, the first insulating layer and the second insulating layer having a via hole for exposing the other of the source electrode and the drain electrode; and a pixel electrode formed on the second insulating layer and electrically connected to the other of the source electrode and the drain electrode, which the power supply line is not electrically connected to, through the via hole in the first insulating layer and the second insulating layer, wherein the power supply line is not formed directly on the same layer as a plurality of gate lines, and the power supply line is not formed directly on the same layer as a plurality of data lines, wherein the via hole in the first insulating layer and the second insulating layer comprises a first via hole in the first insulating layer and a second via hole in the second insulating layer, wherein the first via hole and the second via hole are in direct communication with each other, and wherein the pixel electrode completely overlaps the reflective film.
