Embodiment Construction

[0022] Embodiments of the present invention will cooperate with Figures 1 to Figure 7 The cross-sectional flow chart is described in detail as follows. As shown in Figure 1, first provide a transparent substrate 10, this transparent substrate 10 can be a transparent glass substrate or a transparent plastic substrate, if it is a plastic substrate, its material can be polyethylene terephthalate (polyethyleneterephthalate), polyester ester (polyester), polycarbonate (polycarbonates), polyacrylate (polyacrylates) or polystyrene (polystyrene). A buffer layer can also be formed on the transparent substrate, such as a composite buffer layer composed of a silicon nitride layer and a silicon oxide layer, so as to improve the adhesion between the subsequent film layer and the transparent substrate 10 and improve transparency. The roughness of the surface of the substrate 10. Next, an active layer is formed on the transparent substrate 10, such as a polysilicon layer or an amorphous si...

Abstract

The invention relates to a method for manufacturing an organic electroluminescent display device, which is suitable for preparing a display unit of an active matrix organic electroluminescent display device. The steps include: providing a transparent substrate on which a thin film transistor is formed; and forming a thin film transistor. The metal wires respectively cover part of the surface and sidewalls of the thin film transistor and are respectively connected to a source region and a drain region of the thin film transistor. The metal wires connected to the drain region also extend to the transparent substrate; forming a transparent The electrode is on the transparent substrate and is electrically connected with the metal wire connected to the drain region; and an organic light-emitting layer and a metal electrode are formed on part of the surface of the transparent electrode in order to form an organic light-emitting diode.

Description

technical field [0001] The present invention relates to a method for manufacturing an organic electroluminescent display device, in particular to a method for manufacturing an active matrix organic electroluminescent display device using less manufacturing process photomasks, so as to reduce manufacturing time and save production cost. Background technique [0002] In the new generation of flat-panel display technology, organic electroluminescence display (organic electroluminescence display) is a thin-film laminate display that uses organic compounds as light-emitting materials. The manufacturing process is simple and the like, and the main luminescent principle is to use an organic luminescent layer composed of dye or polymer between the cathode (cathode) and the anode (anode) to emit light. [0003] According to the driving method of the organic electroluminescent display, it can generally be divided into two types: a passive matrix type and an active matrix type. The a...
