Embodiment Construction

[0037] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0038] figure 1 is a cross-sectional view briefly illustrating a flexible display device 100 according to an embodiment of the present invention, in which a top emission type is shown.

[0039] As shown in the figure, the flexible display device 100 of this embodiment is sequentially stacked with an ultra-thin base substrate 110 with a thickness of 50-100 μm, a display portion 120 for presenting images, and a packaging substrate 130 for sealing the display portion 120 . That is, the figure shows a flexible structure in which the display unit 120 is sealed with an extremely thin glass base substrate 110 and a thin-film packaging substrate 130 instead of the conventional thick and hard glass substrate.

[0040] Therefore, compared with the conventional typical structure in which the display unit 120 is surrounded by a thicker glass subst...

Abstract

A method of manufacturing a flexible display device and a carrier substrate for manufacturing the same are disclosed. In one aspect, the method includes preparing a first release area and a first attachment area around the first surface area on a first surface, attaching a base substrate to the first surface, and forming a display unit on the base substrate corresponding to the first release area of the carrier substrate. The method also includes cutting the area of the base substrate corresponding to the first release area of the carrier substrate so as to include the display unit, and separating the cut base substrate from the carrier substrate. Thus, the carrier substrate and the base substrate may be smoothly combined with each other and separated from each other without an additional mask deposition process. Also, damage to a product that may occur during combination and separation of the substrates may be much reduced.

Description

technical field [0001] The present invention relates to a method for manufacturing a flexible display device and a carrier substrate used in the method for manufacturing a flexible display device. Background technique [0002] Display devices such as organic light-emitting display devices can be thinned and softened due to their driving characteristics, and various studies have been conducted on them. [0003] In recent years, a flexible display device in which a display portion is formed on a thin flexible substrate has attracted attention. [0004] However, since the thickness of the aforementioned thin substrate is too thin, it is difficult to handle it in the manufacturing process. Therefore, a relatively thick carrier substrate is generally prepared, a thin substrate is attached thereon, and then processes such as forming a display portion are performed, and finally the carrier substrate is separated. [0005] Therefore, the production efficiency of the overall produc...
