Abstract

Official abstract text for this publication.

A method of manufacturing a flexible display apparatus includes: preparing a substrate; forming a first charge adhesive layer having a first charge on the substrate; forming a second charge adhesive layer having a second charge, which is opposite to the first charge, on the first charge adhesive layer; forming a first charge adhesive pattern and a second charge adhesive pattern by removing an edge of each of the first charge adhesive layer and the second charge adhesive layer; forming a flexible substrate on the substrate on which the first charge adhesive pattern and the second charge adhesive pattern are formed; forming a display unit on the flexible substrate; cutting the substrate, the first charge adhesive pattern, the second charge adhesive pattern, the flexible substrate, and the display unit along a cutting line; and separating the substrate and the flexible substrate.

First claim

Opening claim text (preview).

What is claimed is: 1 . A flexible display apparatus, comprising: a flexible substrate; a circuit element layer disposed on the flexible substrate; a display element layer disposed on the circuit element layer and comprising an organic light emitting diode; an encapsulation layer disposed on the display element layer to seal the display element layer; a charge adhesive layer that contacts a lower surface of the flexible substrate; and a lower charge adhesive layer that contacts a lower surface of the charge adhesive layer, wherein the charge adhesive layer has a charge, and comprises a transparent montmorillonite, wherein the lower charge adhesive layer comprises polyethyleneimine (PEI), and wherein the flexible display apparatus is flexible. 2 . The flexible display apparatus of claim 1 , wherein the charge of the adhesive layer is a first charge, and wherein the lower charge adhesive layer has a second charge opposite the first charge.
