Abstract

The invention discloses a display panel and a method for manufacturing the same. The display panel is characterized in that an auxiliary electrode and a positive electrode of the display panel are arranged on a substrate, a pixel definition layer covers the auxiliary electrode and the positive electrode, the positive electrode and the auxiliary electrode are partially exposed, a negative electrodeisolation column is arranged on exposed portions of the auxiliary electrode, an isolation table of the negative electrode isolation column is electrically conductive and is in contact with the auxiliary electrode, an isolation column body of the negative electrode isolation column is arranged in the isolation table, and a luminescent layer covers the pixel definition layer and exposed portions ofthe positive electrode and the auxiliary electrode and is partitioned by the negative electrode isolation column; a negative electrode covers the luminescent layer, is partitioned by the negative electrode isolation column and is at least in contact with the isolation table. Owing to the mode, the display panel and the method have the advantages that the negative electrode and the auxiliary electrode can be effectively electrically connected with each other, the negative electrode can be individually controlled, and accordingly uniform display effects can be realized by the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Because Organic Light-Emitting Diode (OLED) has display characteristics and quality beyond Liquid Crystal Display (LCD), such as thinner and lighter, short response time, low driving voltage, better display color and Display viewing angle and other advantages, it has received widespread attention. In recent years, the development of OLED has been changing with each passing day. Not only can it produce curved displays, but it is also gradually developing to large sizes. However, there is a problem of voltage drop in the large size, especially for the top emission display panel, the problem of voltage drop caused by the thin cathode needs to be solved urgently, so the auxiliary electrode and cathode isolation column are made in the process to separate the cathode to achieve separate contro...
