Abstract One embodiment of the present invention discloses a rollable display device which includes a roll frame and a flexible display unit wound in a roll shape within the roll frame, wherein the flexible display unit comprises: a flexible substrate; a display layer formed on the flexible substrate; an encapsulation layer sealing the display layer; a protective layer positioned on the encapsulation layer; at least one functional layer positioned between the encapsulation layer and the protective layer; and an adhesive layer interposed between the at least one functional layer and the protective layer. The adhesive layer includes a plurality of first regions and a plurality of second regions alternately disposed between one end and the other end of the flexible display unit, and the modulus of the plurality of first regions and the modulus of the plurality of second regions are different from each other. The present invention provides the rollable display device capable of dispersing accumulated stress. 본 발명의 일 실시예는, 롤 프레임 및 상기 롤 프레임 내에 롤 형태로 감기는 플렉서블 디스플레이부;를 포함하고, 상기 플렉서블 디스플레이부는, 플렉서블 기판; 상기 플렉서블 기판 상에 형성된 디스플레이 층; 상기 디스플레이 층을 밀봉하는 봉지층; 상기 봉지층 상에 위치하는 보호층; 상기 봉지층과 상기 보호층 사이에 위치하는 적어도 하나의 기능층; 및 상기 적어도 하나의 기능층과 상기 보호층 사이에 개재된 접착층;을 포함하고, 상기 접착층은, 상기 플렉서블 디스플레이부의 일단과 타단 사이에서 서로 교번적으로 배치된 복수의 제1 영역들과 복수의 제2 영역들을 포함하고, 상기 복수의 제1 영역들의 모듈러스와, 상기 복수의 제2 영역들의 모듈러스가 서로 상이한 롤러블 디스플레이 장치를 개시한다.
