Abstract
(EN)
Provided is a method for forming a pattern with which moiré is not generated even when superposed on a liquid crystal display, and with which detection sensitivity can be improved by reducing variation in the electrical characteristics of sensors. This method forms, on a light-transmitting support body, a pattern of a light-transmitting electroconductive material having a metal pattern, which has a light-transmitting electroconductive layer having sensor parts electrically connected to terminal parts and dummy parts not electrically connected to the terminal parts, with the sensor parts and/or the dummy parts being in a mesh-like shape. The metal pattern has a mesh-like shape comprising a Voronoi diagram formed with respect to multiple points (generating points) arranged in a plane, and one generating point is arranged with respect to each polygonal shape in a figure formed by filling a plane with polygonal shapes. The position of the generating points in the dummy parts shares in common the center of the polygonal shapes filling the plane, and is a given position within a polygonal shape that has been scaled by enlarging or reducing the size of the polygonal shape by a given ratio (A), or for which the size is unchanged. The positon of at least some of the generating points within the sensor parts shares in common the center of the polygonal shapes filling the plane, and is a given position within a polygonal shape that has been scaled by enlarging or reducing the size of the polygonal shape by a given ratio (B), or for which the size is unchanged. Furthermore, the given ratios (A) and (B) satisfy the relationship A > B.

L'invention concerne un procédé de formation d'un motif avec lequel le moiré n'est pas généré même lorsqu'il est superposé sur un dispositif d'affichage à cristaux liquides, et avec lequel une sensibilité de détection peut être améliorée par la réduction de variation dans les caractéristiques électriques de capteurs. Ce procédé forme, sur un corps de support transmettant la lumière, un motif d'un matériau électroconducteur transmettant la lumière ayant un motif métallique, qui a une couche électroconductrice transmettant la lumière ayant des parties capteur électriquement connectées à des parties de borne et à des parties fictives qui ne sont pas électriquement connectées aux parties de borne, avec les parties de capteur et/ou les parties fictives étant dans une forme analogue à un maillage. Le motif métallique a une forme analogue à un maillage comprenant un diagramme de Voronoi formé par rapport à de multiples points (points de génération) disposés dans un plan, et un point de génération est agencé par rapport à chaque forme polygonale dans une figure formée par remplissage d'un plan avec des formes polygonales. La position de la génération de points dans les parties fictives partage en commun le centre des formes polygonales remplissant le plan, et est une position donnée à l'intérieur d'une forme polygonale qui a été mise à l'échelle, par agrandissement ou réduction de la taille de la forme polygonale par un rapport donné (A), ou pour lequel la taille est inchangée. La position d'au moins certains des points de génération à l'intérieur des parties de capteur partagent en commun le centre des formes polygonales remplissant le plan, et est une position donnée à l'intérieur d'une forme polygonale qui a été mise à l'échelle, par agrandissement ou réduction de la taille de la forme polygonale par un rapport donné (B), ou pour lequel la taille est inchangée. En outre, les rapports donnés (A) et (B) satisfont à la relation A > B.
