Embodiment Construction

[0023] Objects and advantages of the present invention will be described by way of preferred embodiments with reference to the accompanying drawings. refer to Figure 2 to Figure 5 A first embodiment will be described.

[0024] figure 2 A method of manufacturing the flexible display device according to the first embodiment is shown. exist figure 2 Among them, the manufacturing method of the flexible display includes a display device forming process (S21) and a thinning process (S23). In the display device forming process (S21), various patterns are formed on a rigid (non-flexible) substrate. The pattern will be part of the flexible display. For example, image 3 The illustrated electrophoretic display device (EPD) is formed through a display device forming process (S21). EPD utilizes the phenomenon of electrophoresis in which charged particles move to a cathode or an anode when an electric field is applied. In the display device forming process (S21), the EPD is form...

Abstract

A method for manufacturing a flexible display device in which a flexible substrate is acquired by forming display devices on one side of the substrate and thinning the substrate by removing surface portions on an opposite side of the substrate. The thickness of the substrate is changed from a first thickness, which gives rigidity to the substrate to the second thickness, which gives flexibility to the substrate.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2006-112151 filed on November 14, 2006 and No. 10-2006-118457 filed on November 28, 2006, the entire contents of which are hereby incorporated by reference Reference. technical field [0002] The invention relates to a flexible display device and a manufacturing method of the flexible display device. More particularly, the present invention relates to a flexible display device with improved reliability and reduced defects and a method of manufacturing the same. Background technique [0003] In the market of display devices, flat panel displays (FPDs) have replaced cathode ray tube (CRT) displays and become popular. The FPD includes, for example, a liquid crystal display (LCD), a plasma display panel (PDP), or an organic electroluminescent display (OLED). FPDs are lighter and thinner than CRTs. The FPD can be easily applied to a large-sized display system or a portable display system. Glass sub...
