Abstract

La présente invention concerne un panneau tactile au moyen duquel la survenue d'une irisation est réduite, et qui n'est pas enclin à une dégradation de précision de détection d'emplacement même après un traitement sous atmosphère humide à température élevée. Le panneau tactile de la présente invention comprend un panneau d'affichage d'image qui émet une lumière polarisée de manière linéaire, et un capteur de panneau tactile qui est positionné sur un côté pouvant être visualisé du panneau d'affichage d'image. Le capteur de panneau tactile comprend en outre au moins un substrat qui présente une anisotropie optique. Le substrat satisfait la relation de la formule (1) et est positionné de telle sorte que la direction d'oscillation de la lumière polarisée de manière linéaire qui est émise à partir du panneau d'affichage d'image et l'axe lent plan du substrat soient soit orthogonaux, soient parallèles, et l'indice de réfraction (nx) maximal dans le plan du substrat soit de 1,60 ou plus. Formule (1): Nz > 3.0
