Embodiment Construction

[0065] In order to further illustrate the display substrate and the production method thereof, the display device thereof, the following description is described in detail below.

[0066] In the relevant technique, the specific structure of the AMOLED display device typically includes: a substrate, a pixel circuit layer disposed on a substrate, and a plurality of light-emitting units disposed on one side of the pixel circuit layer to the substrate; wherein the pixel circuit layer comprises an array distribution. The pixel circuit, each of which includes a relatively disposed anode pattern and a cathode pattern, and an organic light-emitting material layer disposed between the two, an anode pattern and a pixel circuit, and each anode pattern has a corresponding pixel. The output electrode of the drive transistor in the circuit is electrically connected. When the AMOLED display device is displayed, the AMOLED circuit provides a driving signal as a corresponding anode pattern, while ...

Abstract

The invention discloses a display substrate, a manufacturing method thereof, and a display device, and relates to the field of display technology, and aims to solve the problem of abnormal display of the display device caused by missing or curling edges of an anode pattern. The manufacturer of the display substrate includes the step of making a conductive pattern, which specifically includes: forming a conductive material film layer; forming a fixed structure on the conductive material film layer; patterning the conductive material film layer to form multiple Each conductive pattern includes a middle area and an edge area surrounding the middle area, and the orthographic projection of the fixing structure on the conductive pattern at least partially overlaps with the edge area. The manufacturing method of the display substrate provided by the present invention is used for manufacturing the display substrate.

Description

Technical field [0001] The present invention relates to the field of display, and more particularly to a display substrate and a method of fabricating a display device. Background technique [0002] Active matrix organic light emitting diode (English: Active-Matrix Organic Light EmittingDiode, here: AMOLD) Display device, has been widely concerned with its self-illuminating, wide viewing angle, higher refresh rate and thinner size. The light-emitting unit inside the AMOLED display device includes a relatively set anode pattern and a cathode pattern, and a layer of organic light-emitting material disposed between the two, which provides holes and electrons via an anode pattern and cathode pattern, such that holes and The electrons are complicated in the luminescent material layer, thereby luminrating the organic light-emitting material layer to realize the display function of the AMOLED display device. [0003] However, in the production of an anode pattern, it is easy to make the...
