Abstract

The invention provides a flexible display device and a manufacturing method thereof. The manufacturing method of the flexible display device comprises the following steps: providing a flexible substrate; forming a display device layer on the flexible substrate; forming a first conductive pattern on the display device layer; forming a first dielectric insulation layer on the display device layer and the first conductive pattern, and etching the first dielectric insulation layer to form a trench; and forming a second conductive pattern in the trench, wherein the first conductive pattern and / or the second conductive pattern is made of a self-repair conductive material. According to the flexible display device and the manufacturing method thereof provided by the invention, a metal wire with a relatively quite high length-width ratio and a metal wire with a relatively quite low length-width ratio are formed step by step, the metal wire with the relatively quite high length-width ratio comprises a data line and a grid wire which are both made of the self-repair conductive material and can realize automatic restoration after a fracture, and thus the service life of the flexible display is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display device and a manufacturing method thereof. Background technique [0002] A flexible display is a deformable or bendable display device fabricated on a flexible carrier (also called a flexible substrate). Due to the characteristics of high lightness, impact resistance, flexibility, wearability, and portability, flexible displays are known as one of the most promising products in the 21st century and have been increasingly favored by people. focus on. [0003] A flexible display usually includes a display panel and a peripheral circuit for driving the display panel. The display panel includes a flexible substrate, a pixel array and metal wires, and the pixel array and metal wires are all arranged on the flexible substrate. The peripheral circuit The metal lines are electrically connected to each pixel unit of the pixel array, and the metal lines include data l...
