Summary:The present invention relates to a touch screen capable of improving adhesion of a flexible circuit board to a pad part and a display device including the same. According to an embodiment of the present invention, The touch screen comprises: an insulating substrate including a sensing area and a surrounding area; a plurality of sensing electrodes disposed in the sensing area of the insulating substrate; a plurality of wirings disposed in the surrounding area of the insulating substrate and electrically connected to the plurality of sensing electrodes; a plurality of pads disposed in the surrounding area of the insulating substrate and electrically connected to the plurality of wirings; an optical film disposed on an upper part including the plurality of sensing electrodes; a flexible circuit board electrically connected to the plurality of pads; and a reinforcing member disposed on the flexible circuit board corresponding to the plurality of pads, wherein the height from the insulating substrate to a surface of the reinforcing member is equal to the height from the insulating substrate to a surface of the optical film. 본 발명의 실시예는 터치스크린 및 그를 구비하는 표시장치에 관한 것으로, 터치스크린은 감지영역 및 주변영역을 포함하는 절연기판, 상기 절연기판의 상기 감지영역에 배치된 복수의 감지전극, 상기 절연기판의 상기 주변영역에 배치되며 상기 복수의 감지전극과 전기적으로 연결된 복수의 배선, 상기 절연기판의 상기 주변영역에 배치되며 상기 복수의 배선에 전기적으로 연결된 복수의 패드, 상기 복수의 감지전극을 포함하는 상부에 배치된 광학필름, 상기 복수의 패드에 전기적으로 연결된 연성회로기판, 및 상기 복수의 패드에 대응하는 상기 연성회로기판 상에 배치된 보강부재를 포함하며, 상기 절연기판에서 상기 보강부재 표면까지의 높이는 상기 절연기판에서 상기 광학필름 표면까지의 높이와 같다.
