Abstract

The invention discloses a foldable display device which comprises a first substrate and a first optical adhesive film located on one side of the first substrate, the optical adhesive film comprises afirst solidification layer and a flowing layer which are arranged in a stacked mode, the first curing layer is used for being attached to the first substrate, the mobility of the flowing layer is higher than that of the first curing layer, and the flowing layer is used for improving the mobility of the first optical adhesive film. The invention further discloses a manufacturing method of the foldable display device. The first curing layer is poor in mobility and good in stickiness, the flowing layer has the good mobility, and the shape recovery speed of the whole optical adhesive film is increased; in the thickness direction of the optical adhesive film, the optical adhesive film has different magnitudes of mobility, the good sticky effect is achieved, the good mobility is kept, and the using requirement of the foldable display device for frequent folding and unfolding is met.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a foldable display device and a manufacturing method of the foldable display device. Background technique [0002] In recent years, the rapid development of organic light-emitting diode (OLED) display technology has promoted the rapid entry of curved surface and flexible display touch products into the market, and major panel manufacturers have invested heavily in the layout of flexible display touch projects. The different layers of the touch display module are bonded and fixed by Optically Clear Adhesive (OCA). Adhesive properties and better ink absorption capacity also need to have better bending resistance. In other words, when OCA glue is bent, it needs to be able to effectively slow down the superposition of stress and promote the release of stress. [0003] In the prior art, by choosing OCA glue with high fluidity, the transmission of stress generated by folding ...
