Organic light-emitting device and manufacturing method thereof

Abstract

The invention discloses an organic light-emitting device and a manufacturing method thereof. The organic light-emitting device comprises a substrate, first isolation columns, transparent electrode layers and organic light-emitting layers, wherein the first isolation columns are formed on the substrate and arranged in the first direction of the substrate; the transparent electrode layers are formed on the substrate between two adjacent first isolation columns and on the first isolation columns; the transparent electrode layers formed on the substrate are mutually separated from the transparent electrode layers formed on the first isolation columns; and the organic light-emitting layers are formed on the corresponding transparent electrode layers on the substrate. Therefore, through utilization of a height difference between each first isolation column and the substrate, the transparent electrode layers in a second direction are naturally separated from each other, and an additional transparent electrode layer etching procedure is not needed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting device and a manufacturing method thereof. Background technique [0002] With the continuous development of display technology, liquid crystal displays and organic light-emitting diode (OLED, Organic Light-Emitting Diode) displays are widely used due to their advantages of low driving voltage, low energy consumption, light weight, and thin thickness. [0003] figure 1 Shows a cross-sectional view of an existing PMOLED (Passive Matrix Organic Light-Emitting Diode), the usual manufacturing method is to first coat transparent conductive metal materials such as ITO, and then coat such as Mo / Conductive metal materials such as Al / Mo, and then etch conductive metal materials such as Mo / Al / Mo to form wiring layer 12, and then etch transparent conductive metal materials such as ITO to form transparent electrode layer 13, and finally form isolation Pillar 14 ,...
