Problems solved by technology

A phenomenon in which the display screen is shifted or deformed due to unevenness generated between the folded portion and the non-folded portion
In addition, conventional foldable display devices employing rear covers have other problems in that the flexible foldable part sags or curls upward due to stress concentration after being folded many times, and is cured or deformed in appearance under high temperature and high humidity conditions

Abstract

Disclosed is a foldable display device capable of preventing distortion of a folding part of a display screen due to deformation of the folding part. The foldable display device includes a display panel including a folding part and non-folding parts, and a back cover attached to the rear surface of the display panel via an adhesive layer, wherein the back cover includes folding patterns and open patterns, both of which are disposed at the folding part, and unevenness compensation patterns disposed on areas of a surface of the back cover contacting the adhesive layer, the areas of the surface of the back cover corresponding to the non-folding parts. The unevenness compensation patterns may be a plurality of open patterns, which are fully formed through the back cover, or may be a pluralityof grooves, which are not fully formed through the back cover.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2016-0184477 filed on December 30, 2016, which is incorporated herein by reference as if fully set forth herein. technical field [0003] The present invention relates to a foldable display device, and more particularly, to a foldable display device capable of preventing deformation of a folded portion of a display screen due to deformation of the folded portion. Background technique [0004] Image display devices that realize various information on a screen are core technologies in the information and communication age, and are moving toward becoming thinner, lighter, more portable, and having higher performance. In response thereto, flat panel display devices thinner and lighter than cathode ray tubes (CRTs), such as organic light emitting display devices that control the amount of light emitted from an organic light emitting layer to display ima...
