Problems solved by technology

However, after the OLED display device has been folded many times, the surroundings of the contact holes are easily affected by external stress, so that the source / drain (S / D) electrode metal lines of the Active Area (AA) are easily damaged near the contact holes. Fracture or detachment, which in turn damages the flexible OLED device

Abstract

The invention discloses a flexible display panel and a display device; the flexible display panel comprises a substrate, an active layer, a gate insulation layer, a first grid electrode and an inter-layer insulation layer laminated in order; the flexible display panel also comprises a source electrode contact hole, a drain electrode contact hole, an organic protective layer, a source electrode anda drain electrode; the active layer comprises contact doped areas arranged on two ends; the source electrode contact hole and the drain electrode contact hole respectively penetrate the first gate insulation layer and the inter-layer insulation layer, thus exposing the contact doped areas of active layer; the organic protective layer is arranged on the inter-layer insulation layer and extends tohole walls of the source electrode contact hole and the drain electrode contact hole; the source electrode and the drain electrode are arranged on the organic protective layer, and electrically connected with the contact doped areas respectively via the source electrode contact hole and the drain electrode contact hole. The flexible display panel adds the organic protective layer so as to mitigatethe stress received in areas around the source / drain electrode contact holes, thus preventing damages caused by folding.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel and a display device. Background technique [0002] With the development of display technologies, consumers have more and more diversified and personalized demands on display methods and display effects of display devices. Compared with traditional display devices, flexible display panels have the advantages of being foldable, transparent, curved, flexible and stretchable, and are widely favored by consumers. [0003] Flexible display panels (such as flexible organic light-emitting diodes (Organic Light-Emitting Diode, OLED for short), which usually need to fold the entire display screen multiple times. However, after the OLED display device is folded many times, the surroundings of the contact holes are vulnerable to external Due to the influence of the stress, the source / drain (S / D) electrode metal lines in the Active Area (AA) are easy to bre...
