Abstract

The invention discloses an electric light displaying device including a film transistor, a nontransparent electrode, a nontransparent layer, a media layer and a transparent electrode. The film transistor is arranged on the base board, and it is covered by a middle insulating layer. The nontransparent electrode and the nontransparent layers are arranged above the middle insulating layer in order; the nontransparent electrode is connected to the nontransparent transistor. The nontransparent layer has an aperture and exposes part of nontransparent electrode. The media layer is arranged on the aperture part. The transparent electrode is arranged above the nontransparent. The invention also discloses the preparing method for the device.

Description

technical field [0001] The present invention relates to a flat display device, in particular to a top emission type electro-luminescence display device (electro-luminescence device) and a manufacturing method thereof. Background technique [0002] Electroluminescent devices, such as organic light emitting diodes (OLEDs), are self-luminous devices using organic materials. Typically, an OLED includes: an anode, a cathode, and an electro-luminescence medium layer (EML) disposed between the anode and the cathode. When a potential difference is applied between the cathode and the anode, electrons and holes are respectively injected into the electroluminescence medium layer from the cathode and the anode to recombine and release energy in the form of light. [0003] figure 1 A schematic cross-sectional view of a conventional bottom emitting electroluminescent display device is shown. Please refer to figure 1 , a buffer layer 102 is formed on a substrate 100, and a thin film tr...
