The invention provides an organic display device and a manufacturing method thereof. The organic display device comprises a scan line, a data line and a power line, wherein a region defined by intersecting the scan line, the data line and the power line is provided with a display region; the display region is provided with organic light-emitting diodes, and the organic light-emitting diodes comprise anode layers; and a conducting layer is formed on the power line, wherein the anode layers of the organic light-emitting diodse and the conducting layer are formed by etching based on the same material layer. The conducting layer shares the conducting task, so that the size of the power line can be reduced, for example, the width of the power line can be reduced, the aperture ratio of the organic display device can be increased, the problem of voltage drop can also be avoided, and each organic light-emitting diode emits light evenly.
Description
【Technical field】 [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode display and a manufacturing method thereof. 【Background technique】 [0002] Organic Electroluminesence Display (OELD) is a new generation display device, which generally uses Organic Light Emitting Diode (OLED) as a light-emitting display component. [0003] An organic light-emitting diode emits light by sandwiching an organic light-emitting material between a transparent anode and a metal reflective cathode, and applying a voltage to the organic light-emitting material. Because organic electro-laser displays do not require liquid crystals and traditional backlight modules, they can be made lighter and thinner. Compared with other types of flat panel display devices, OLEDs consume less power, and OLEDs can work in a wide temperature range. The cost is low, so it is more and more widely used. [0004] see figure 1 , figure 1 is a schematic cr...
