Embodiment Construction
[0028] Reference will now be made in detail to the preferred mode of carrying out the invention, examples of which are illustrated in the accompanying drawings. In the drawings, the thicknesses of specific regions to be shown are exaggerated in order to facilitate understanding of the present invention. An exemplary embodiment of the present invention will be described below with reference to FIGS. 1A to 11 .
[0029] As shown in FIGS. 1A to 1C, the manufacturing process of the flexible liquid crystal display according to the present invention is mainly divided into a substrate bonding process (S1), an upper array substrate manufacturing process (S2), a lower array substrate manufacturing process (S3), a liquid crystal process ( S4), peeling process (S5) and module process (S6). The substrate bonding process S1 is a process for bonding the flexible substrate 45 that provides flexibility to the display device and the rigid substrate 47 that provides support to accurately perfo...

Abstract
A fabricating method of a flexible display device includes the steps of providing an adhesive layer including a first adhesive material on a first surface of a support film, a second adhesive material on a second surface of the support film such that an adhesive strength of the second adhesive material is lower than an adhesive strength of the first adhesive material, and a third adhesive material encompassing an edge of the second adhesive material such that an adhesive strength of the third adhesive material is higher than the adhesive strength of the second adhesive material; a first passivation film adhered to the first surface of the support film with the first adhesive material therebetween; and a second passivation film adhered to the second surface of the support film with the second adhesive material and the third adhesive material therebetween; peeling the first passivation film from the adhesive layer; adhering a rigid substrate to the first adhesive material; peeling the second passivation film from the adhesive layer; and adhering a flexible substrate onto the second and third adhesive materials.
Description
[0001] This application claims the benefit of application number P2005-40240 filed in Korea on May 13, 2005 and application number P2005-63930 filed in Korea on July 14, 2005, the entire contents of which are incorporated herein by reference . technical field [0002] The invention relates to a flexible display, in particular to a manufacturing method for preventing a substrate from falling off during the manufacturing process of the flexible display. Background technique [0003] Recently, the display market has changed rapidly, and the central position has been taken by flat panel display (FPD) devices. It is easy to manufacture the FPD device as a large-sized, thin and light display device. The FPD device includes a liquid crystal display (LCD), a plasma display panel (PDP), an organic electroluminescent display (OLED), and the like. However, existing liquid crystal displays, plasma display panels, and organic electroluminescent displays are all made of glass substrates...
