Embodiment Construction

[0028] It has been mentioned in the background art that the interconnection structure of the flexible display device is easily broken, resulting in failure of the flexible display device. The inventors found that this is because metal wires (such as gold wires, silver wires or copper wires) are usually used to form the interconnect structure, and the distribution of the metal wires is diversified, such as the pattern of the metal wires is a straight line One or more of shape, arc shape, V-shape, wherein, the included angle of the V-shape can be a right angle, an obtuse angle or an acute angle.

[0029] figure 1 It is a top view structure diagram of a display substrate in a flexible display device. like figure 1 As shown, the display substrate includes a flexible substrate 10 and an interconnection structure 11 formed on the flexible substrate 10. The pattern of the metal lines of the interconnection structure 11 is distributed in a V shape, that is, the interconnection struc...

Abstract

The invention discloses an interconnection line structure, a display substrate and a manufacturing method thereof, and a display device. The interconnection line structure is provided with a first region and a second region interconnected with each other, the stress of the second region is greater than the stress of the first region, the first region comprises a conductive line, and the second region comprises a nanometer metal wire. The nanometer metal wire not only has good electrical conductivity, but also has good ductility (bending resistance), therefore, the nanometer metal wire is not easy to be broken during the process of being bent, so that the mechanical reliability of the interconnection line structure can be effectively improved. Thereby, the reliability of the display devicecan be improved by applying the display substrate including the interconnection line structure to the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an interconnect structure, a display substrate and a manufacturing method thereof, and a display device. Background technique [0002] Flexible display devices have their own powerful advantages, such as easy to carry, bendable, and can be deformed at will. At present, flexible display technology is becoming more and more mature, flexible screens will gradually enter people's lives, and flexible mobile devices will gradually become The main tool of daily life, the industry predicts that flexible mobile devices will gradually replace traditional mobile devices (mobile phones, tablets, etc.) in the near future. [0003] In flexible display devices, the interconnection structure is one of the core structures in flexible display devices, such as the interconnection structure of thin film transistor array electrodes, the interconnection structure of organic light-emitting layer elect...
