PATTERN SUBSTRATE AND TOUCH PANEL USING THE SAME

摘要

A touchscreen display device includes a display module and an electrically conductive and light transmissive layer provided over the display module to allow detection of touch input. The electrically conductive and light transmissive layer includes a transparent substrate and a transparent layer provided over the transparent substrate. The transparent layer has first and second surfaces, which are opposing surfaces, and the first surface faces the transparent substrate. The second surface includes a plurality of protrusions extending in different directions such that the plurality of first protrusions intersect to form recess regions on the second surface. The recess regions include a plurality of second protrusions, and the second protrusions have a height and a width less than the first protrusions. At least one metallic wiring layer is formed on the plurality of first protrusions including at locations where the first protrusions intersect.
