Embodiment Construction

[0038] Hereinafter, embodiments of the inventive concept will be described with reference to the accompanying drawings. In this specification, it will also be understood that when a component (or region, layer, section) is referred to as being "on", "connected to" or "coupled to" another component, it may be directly Connected / coupled to / to a component, or there may also be an intervening third component.

[0039] The same reference numerals denote the same elements throughout. Also, in the drawings, the thicknesses, ratios, and sizes of components are exaggerated for clarity of illustration. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0040] It should be understood that although terms such as "first" and "second" are used herein to describe various elements, these elements should not be limited by these terms. Terms are only used to distinguish one component from the other. For example, a first element termed a firs...

Abstract

The present invention relates to a window member and a display device including the same. The window member comprises: a first base member having a first thickness, a first impact absorbing layer disposed on one surface of the first base member and having a storage modulus less than that of the first base member and a second thickness, a first hard coating layer disposed on the first impact absorbing layer, and a second hard coating layer disposed on the other surface that is opposite to the one surface of the first base member. Here, a ratio of the second thickness to the first thickness is equal to or greater than about 1.0 and equal to or less than about 1.67. The first base member is bent with respect to a bending axis extending in one direction.

Description

[0001] Related Application Cross Reference [0002] This patent application claims priority from Korean Patent Application No. 10-2017-0153371 filed on November 16, 2017, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure herein relates to a window member and a display device including the window member, and more particularly, to a window member having flexibility characteristics and improved impact resistance with respect to external impacts and a display device including the window member. Background technique [0004] In recent years, bendable or foldable electronic devices have been actively developed. Such flexible electronic devices include electronic panels such as flexible display panels or flexible touch panels, and various external members. The external components have different functions respectively. Each exterior member is disposed on at least one of the one surface and the other surface of the e...
