Abstract

The invention provides a display panel and a manufacturing method thereof.The display panel is provided with a display area and a binding area, the display panel comprises a substrate, a circuit layer, a flat layer, an anode, a pixel definition layer, a light-emitting layer and a cathode, the substrate comprises a second insulating layer, the circuit layer is arranged on the second insulating layer, and the flat layer is arranged on the second insulating layer; the circuit layer comprises a circuit pattern arranged in the display area and a plurality of connecting wires, the connecting wires extend to the binding area from the circuit pattern, the pixel definition layer comprises a plurality of pixel retaining walls arranged on the flat layer and a plurality of bonding retaining walls arranged in the binding area, one part of each bonding retaining wall is pressed on the edge of the corresponding connecting wire, and the other part of each bonding retaining wall is pressed on the edge of the corresponding connecting wire. And the other part is pressed on the second insulating layer. The bonding retaining wall is arranged on the pixel definition layer, so that the reliability of the circuit layer in the binding area is improved, and the problem that the circuit layer in the binding area falls off is greatly solved.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a display panel and a manufacturing method thereof. Background technique [0002] In the current production of medium and large size OLED products, due to the direct contact between the PAD layer (circuit layer, made of MoTi and other materials) and the PVS layer (insulation layer, made of organic materials) in the film layer design of the binding area, the two One is an inorganic film layer and the other is an organic film layer, so the adhesion between them is poor. Because the PAD layer is located on the outermost surface and is in a bare state, if the adhesion between the PAD layer and the PVS layer is not good and there is no other film protection at the boundary of the contact surface, it is easy to fall off. Especially when the OLED display panel is reworked, the PAD layer in the binding area is prone to obvious peeling off. This problem will direct...
