Abstract
A top emission active matrix organic light-emitting display device is provided. The display device has a metallic-shielding layer underneath an anode layer so that light from an organic light-emitting layer is prevented from penetrating into the channel layer of a thin film transistor to induce a photoelectric leakage current. The metallic shielding layer also permits the extension of the anode layer into area above the thin film transistor so that light-emitting area of each pixel structure is increased. High conductivity of the shielding layer is also utilized to boost the electrical conductivity of the anode layer so that the device carries a uniform current resulting in a longer working life.
