Abstract
A touch panel fabricating method is disclosed. A first conductive layer, a second conductive layer and a first photo-resist layer are sequentially formed on a substrate. Next, the first photo-resist layer is patterned by using a gray-level mask. Then, the first conductive layer and the second conductive layer are etched according to the patterned first photo-resist layer to define a plurality of first sensing electrodes. Then, an insulation layer is formed on the substrate and the first sensing electrodes. The insulation layer is patterned by using a gray-level mask. Then, a third conductive layer is formed on the patterned insulation layer. A second photo-resist layer is formed on the third conductive layer. The second photo-resist layer is patterned to expose partial third conductive layer. Then, the exposed third conductive layer is etched to define a plurality of second sensing electrodes.
