Problems solved by technology
[0005] However, when the light-transmitting electrode pattern is extended to the non-transmitting region in this way, since the length of the light-transmitting electrode pattern whose resistance value is higher than that of the metal becomes longer, there is a problem that signal transmission characteristics deteriorate.
In particular, the ITO (Indium Tin Oxide) film generally used as a light-transmitting electrode pattern has a higher resistance value than metals such as aluminum or molybdenum, so the transmission characteristics are significantly deteriorated.

Embodiment Construction
[0058] Hereinafter, a pointer detection device according to an embodiment to which the present invention is applied will be described with reference to the drawings.
[0059] figure 1 is a diagram showing a schematic appearance shape of a pointer detection device according to an embodiment. The pointing body detection device of this embodiment includes: a display device 200 such as an LCD (Liquid Crystal Display) having a display area for displaying information; position detection sensor 100 . In addition, the "indicator" also includes: a pen with a conductive body at the tip, and a pen that detects by attracting an electrostatic field on the same principle as finger detection through a path connected to the ground of the human body, and a pen that transmits a signal from the pen itself.
[0060] figure 1 Among them, the position detection sensor 100 has a transmission area 110 that can be observed through the display area of the display device 200 arranged in an overla...

The present invention provides a pointer detection device, a position detection sensor, and a manufacturing method thereof capable of improving signal transmission characteristics in a detection conductor when performing position detection in a region including the end of a transmission region. The position detection sensor (100) has: a first glass substrate (15), a transmission conductor group (12) composed of a plurality of transparent conductors arranged on one surface of the first glass substrate (15), A receiving conductor group (14) composed of a plurality of transparent conductors in the crossing direction of the group (12), a signal detection circuit (34) for detecting a signal generated by the receiving conductor group (14) according to the position indication of the pointer (300), etc. A metal wiring pattern (11C) arranged on the surface of the section included in the non-transmission area of the transmission conductor group (12).
Description
technical field [0001] The present invention relates to a pointer detection device mounted on a surface of a display screen for detecting the position of a pointer, a position detection sensor, and a method of manufacturing the position detection sensor. Background technique [0002] Conventionally, a capacitive input device is known, which is arranged on the surface of a display screen of a liquid crystal display device, detects its position when touched by a user's finger, etc., and provides information corresponding to a displayed instruction image. input (for example, refer to Patent Document 1). In this capacitive input device, translucent electrode patterns intersecting each other are formed on the surface of a translucent substrate, and the position of the user's finger is detected from a change in capacitance generated when the user's finger touches the surface. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2009-259203 (pp. 5-15, Figure 1-11 ) [0004]...
