Abstract

A pixel structure of an organic electroluminescence apparatus includes at least an active device connected to a scan line and a data line, a first electrode, a dielectric material layer, a first isolating layer, a second isolating layer, an organic light-emitting material layer and a second electrode. The dielectric material layer is disposed on the first electrode and has a first opening to expose the first electrode. The first isolating layer disposed on the dielectric material layer includes an oxide semiconductor material and has a second opening to expose the first electrode. The second isolating layer is disposed on the first isolating layer and has a third opening to expose the first electrode in the first opening and the first isolating layer in a sidewall of the second opening. The organic light-emitting material layer is in the third opening. The second electrode is on the organic light-emitting layer.
