Description

FLEXIBLE PLATE WITH DUMMY

The present invention relates to a flexible plate having an expandable fixed dummy, and more particularly, in a plate having a bending part therein, an assembly operation of the plate by extending the dummy connecting both mounting parts that can flow around the bending part to each other It relates to a flexible plate having an expandable fixed dummy capable of preventing deformation of the sea plate.

A general display device has rapidly changed to a flat panel display (hereinafter referred to as "FPD") instead of a cathode-ray tube (CRT). FPD includes a liquid crystal display (LCD), a plasma display panel (PDP), an organic light emitting display (LED), and the like. These FPDs have advantages in that they are lightweight and thin compared to CRTs, and are advantageous in increasing the size. On the other hand, FPD uses a glass substrate to withstand high heat generated during the manufacturing process, so there is a limit in providing light weight, thinness and flexibility. Accordingly, recently, a flexible display device manufactured by using a flexible material such as plastic or the like instead of a non-flexible glass substrate to maintain display performance even when bent like paper has been developed.
