Abstract:
1. A substrate assembly of an active matrix organic electro luminescent display (ELD) device, comprising: a substrate; first and second active layers formed of polycrystalline silicon on the substrate; first source and drain regions and second source and drain regions, the first source and drain regions neighboring the first active layer and the second source and drain regions neighboring the second active layer; a gate insulating layer on the first and second active layers; first and second gate electrodes on the gate insulating layer; a first inter layer on the first and second gate electrodes; an anode electrode and a capacitor electrode on the first inter layer; a first passivation layer on the anode electrode and the capacitor electrode; a power line on the first passivation layer; first source and drain electrodes on the first passivation layer, the first source electrode being connected to the first source region and the first drain electrode being connected to the first drain region; second source and drain electrodes on the first passivation layer, the second source electrode being connected to the second source region, the power line and the capacitor electrode and the second drain electrode being connected to the second drain region and the anode electrode; and a second passivation layer on the first source and drain electrodes and the second source and drain electrodes, the second passivation layer having a bank that exposes the anode electrode.
