Abstract

The invention relates to the technical field of display and discloses a flexible substrate, a manufacturing method thereof and a display device comprising the flexible substrate. The flexible substrate comprises a flexible substrate body and a plurality of insulating layers formed on the flexible substrate body, and via holes are formed in at least one insulating layer and filled with organic materials. In the flexible substrate, the organic materials in the via holes of the insulating layers can absorb stress, the stress of the flexible substrate generated during bending can be reduced, the insulating layers are prevented from fracturing due to overlarge stress, and accordingly, the flexible substrate is high in reliability and good in bendability.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to a flexible substrate, a manufacturing method thereof, and a display device containing the flexible substrate. Background technique

[0002] A flexible display device is a display device formed based on a flexible base material. Since the flexible display device has the characteristics of rollability, wide viewing angle, and portability, the flexible display device has broad application prospects and good market potential in portable products and most display application fields.

[0003] The array substrate of the flexible display device in the prior art usually uses an insulating layer, for example, an inorganic buffer layer, a gate insulating layer, an interlayer insulating layer, and a passivation layer. The above-mentioned insulating layer is usually made of SiNx or SiOx material, which has poor toughness. Therefore, when the flexible display device is bent, the insu...
