FRONT PLATE FOR TOUCH PANEL, INTEGRATED SENSOR SUBSTRATE OF FRONT PLATE FOR TOUCH PANEL AND TOUCH PANEL SENSOR, AND DISPLAY UNIT EQUIPPED WITH THESE

摘要

PROBLEM TO BE SOLVED: To improve a light-shielding property, volume resistivity and dielectric constant in a frame part of a front plate for a touch panel.;SOLUTION: A front plate for a touch panel is used for a touch panel. The front plate has a frame part formed at a peripheral part on one surface thereof, to partition display areas of a predetermined shape. The frame part includes carbon and formed by a screen printing method. In the frame part, optical density (OD value) is 4.0 or more, and volume resistivity is 1.0×10⁹ Ω cm or more, and dielectric constant is 35 or less.;COPYRIGHT: (C)2014,JPO&INPIT
