Embodiment Construction

[0037] Embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. Like reference numerals denote like elements in the drawings, and thus their repeated descriptions will be omitted. Also, the size of components may be exaggerated for convenience and clarity of description.

[0038] The embodiments described below are illustrative only, and various modifications can be derived from the embodiments. For example, when it is described that a layer is "on" or "over" a substrate or another layer, the layer may be directly on the substrate or another layer, or a third layer may be present therebetween.

[0039] Technical terms used in the specification are only for describing the embodiments and are not used to limit the present invention. In this specification, expressions in the singular include expressions in the plural unless they are clearly different from each other in context. "Includes" and / or "has" in the description...

Abstract

Disclosed is a display apparatus. The display apparatus includes: a display module including a flexible substrate, a display panel, and an encapsulation film; a lower module disposed below the display module; an upper module disposed on the display module; and an elasticity-adjusting layer disposed on or below the display module to adjust a position of a neutral plane in bending of the display apparatus, wherein an elastic modulus of the elasticity-adjusting layer is less than that of at least one of the display module, the lower module, or the upper module, so as to position the neutral plane within or proximate to the display module.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2013-0067942 filed with the Korean Patent Office on Jun. 13, 2013, the entire contents of which are hereby incorporated by reference. technical field [0003] Embodiments of the present invention generally relate to display devices and methods of manufacturing the same, and more particularly, to display devices with improved bending properties and methods of manufacturing the same. Background technique [0004] With the recent rapid advancement of semiconductor technology, the performance of display devices has been improved to increase the screen size of flat panel display devices, reduce their weight, etc., thereby resulting in a huge increase in demand for such flat panel display devices. [0005] Examples of such flat panel displays include Liquid Crystal Displays (LCD), Plasma Display Devices (PDP), Field Emission Display Devices (F...
