Display Opening Structure Using Partition Walls to Prevent Layer Peeling

The patent applies preliminary action by forming partition walls at the peripheral area before removing the insulating layer. These partition walls are positioned to prevent lifting and peeling of the plurality of layers that would otherwise occur during the insulating layer removal process. By preparing this protective structure in advance, the patent eliminates the need for complex post-removal repairs while maintaining layer stability throughout the opening formation process.

The partition walls serve as an intermediary structure between the insulating layer and the plurality of layers. During the insulating layer removal process, these partition walls act as a mediator that absorbs and distributes the adhesive forces, preventing direct pulling and peeling of the plurality of layers. This intermediary structure enables safe removal of the insulating layer while maintaining overall layer integrity.

The patent applies the taking out principle by extracting the harmful adhesive force effect through the introduction of partition walls. These partition walls are specifically designed to be removed after serving their protective function during insulating layer removal. By extracting this intermediate protective structure after use, the patent eliminates the source of adhesive forces that would otherwise cause layer lifting, while having enjoyed the reliability benefits during the critical etching and removal phases.

The partition walls function as disposable temporary structures that provide necessary protection during the etching and insulating layer removal processes. These partition walls are designed to be removed after serving their protective purpose, similar to sacrificial structures in manufacturing. This approach allows the use of the insulating layer as a reliable buffer during etching while eliminating the harmful adhesive effects afterward.
