触控面板以及其制作方法
摘要：
一种触控面板以及其制作方法，该触控面板的制作方法包括于第一基板上形成透明导电层，于透明导电层上形成第一图案化保护层，于第一图案化保护层及透明导电层上形成金属层。然后于金属层上形成第二图案化保护层，其中第一图案化保护层包括重叠部，其与一部分的第二图案化保护层重叠。进行图案化工艺，移除未被第二图案化保护层覆盖的金属层以及未被第一图案化保护层或/及第二图案化保护层覆盖的透明导电层，以形成触控感测电极、下部导线以及上部导线。移除第二图案化保护层以及未被金属层覆盖的第一图案化保护层，并留下第一图案化保护层的重叠部。本发明可减少工艺的数量而降低制造的成本。
摘要（英）：

A touch panel and a manufacturing method thereof are disclosed. The method includes forming a transparent conductive layer on a first substrate; forming a first patterned protective layer on the transparent conductive layer; forming a metal layer on the first patterned protective layer and the transparent conductive layer; forming a second patterned protective layer on the metal layer, with the first patterned protective layer including an overlapping portion which overlaps a portion of the second patterned protective layer; performing a patterning process to remove the metal layer uncovered by the second patterned protective layer and to remove the transparent conductive layer uncovered by the first patterned protective layer and/or the second patterned protective layer, so as to form touch sensing electrodes, a bottom conductive line and a top conductive line; and removing the first patterned protective layer uncovered by the metal layer and the second patterned protective layer, with the overlapping portion of the first patterned protective layer remained. According to the touch panel and the method, the number of processes can be reduced so as to reduce the manufacturing cost.
