Abstract
The present disclosure relates to a multi-layer film. The multi-layer film may include a first region and a second region. The first region may include a first bonding layer and a first planarization layer directly contacted with each other. The second region includes a second bonding layer, a second planarization layer, and an intervention layer between the second bonding layer and the second planarization layer.
Claims18
A multi-layer film, comprising:
- a first region and a second region, wherein:
- the first region comprises a first bonding layer and a first planarization layer directly contacted with each other;
- and
- the second region comprises a second bonding layer, a second planarization layer, and an intervention layer between the second bonding layer and the second planarization layer,
- wherein the intervention layer comprises a first support layer;
- and
- the intervention layer further comprises a first barrier layer between the first support layer and the second bonding layer.
A multi-layer film, comprising:
- a first region and a second region, wherein:
- the first region comprises a first bonding layer and a first planarization layer directly contacted with each other;
- and
- the second region comprises a second bonding layer, a second planarization layer, and an intervention layer between the second bonding layer and the second planarization layer;
- wherein the multi-layer film further comprises a second support layer covering both the first region and the second region, wherein a first interfacial bonding strength between the second support layer and the first bonding layer is substantially larger than a second interfacial bonding strength between the second support layer and the second bonding layer.
A method of manufacturing a display panel, the display panel including a multi-layer film having a first region and a second region and a display layer on the multi-layer film, comprising:
- forming an intervention film on a substrate;
- forming a first bonding layer in the first region and a second bonding layer in the second region;
- removing the intervention film in the first region and the substrate to form an intervention layer;
- and
- forming a planarization film on the intervention layer, the planarization film comprising a first planarization layer in the first region and a second planarization layer in the second region;
- wherein the first region comprises the first bonding layer and the first planarization layer directly contacted with each other;
- and
- the second region comprises the second bonding layer, the second planarization layer, and the intervention layer between the second bonding layer and the second planarization layer.
