A digitizer comprises: a substrate layer including a folding portion; a lower conductive layer arranged on the substrate layer; an interlayer insulation layer which is formed on the substrate layer to cover the lower conductive layer, and which has an open portion or a recess formed in the folding portion; and an upper conductive layer arranged on the interlayer insulation layer and the substrate layer and electrically connected to the lower conductive layer. The interlayer insulation layer is at least partially removed from the folding portion so that folding reliability can be improved. Un numériseur comprend : une couche de substrat comprenant une partie de pliage ; une couche conductrice inférieure disposée sur la couche de substrat ; une couche d'isolation intercouche qui est formée sur la couche de substrat pour recouvrir la couche conductrice inférieure, et qui a une partie ouverte ou un évidement formé dans la partie de pliage ; et une couche conductrice supérieure disposée sur la couche d'isolation intercouche et la couche de substrat et connectée électriquement à la couche conductrice inférieure. La couche d'isolation intercouche est au moins partiellement retirée de la partie de pliage de sorte que la fiabilité de pliage peut être améliorée. 디지타이저는 폴딩부를 포함하는 기재층, 기재층의 상면 상에 배치된 하부 도전층, 기재층의 상면 상에 형성되어 하부 도전층을 덮고 폴딩부에서 개구부 혹은 리세스가 형성된 층간 절연층, 및 층간 절연층 및 기재층의 상면 상에 배치되고 상기 하부 도전층과 전기적으로 연결되는 상부 도전층을 포함한다. 폴딩부에서 층간 절연층이 적어도 부분적으로 제거되어 폴딩 신뢰성이 향상될 수 있다.
