Patent ID: 8466467

Claim:
An organic light-emitting display apparatus comprising: an active layer formed on a substrate; a first insulation layer formed on the active layer; a gate electrode, separated from the active layer by the first insulation layer, the gate electrode having, in stacked sequence, a first conductive layer formed on the first insulation layer, and comprising a transparent conductive material, and a second conductive layer comprising a metal; a pixel electrode having, in stacked sequence, a first electrode layer, comprising a transparent conductive material, formed on the first insulation layer and spaced apart from the gate electrode, a second electrode layer formed of a semi-permeable metal comprising pores and nano-sized silver (Ag) particles, and a third electrode layer comprising a metal; a second insulation layer formed on the gate electrode and the pixel electrode; source/drain electrodes electrically connected to the active layer via the second insulation layer; an electro-luminescence (EL) layer formed on the second electrode layer of the pixel electrode; and an opposite electrode formed on the EL layer to face the pixel electrode.
