THE TOUCH PANEL AND THE MANUFACTURING METHOD OF THE CAPACITIVE OVERLAY WHERE THE REFLECTIVITY IMPROVES

摘要

PURPOSE: A touch panel, and a manufacturing method of a capacitive overlay which improves the reflectivity thereof are provided to prevent the exposure of an electronic circuit pattern of a capacitance-type display by minimizing the reflectance difference between a substrate and a TCO(Transparent Conducting Oxide) layer even after an etching process. CONSTITUTION: An optical layer(30) is formed in order for the reflectance difference to a TCO(Transparent Conducting Oxide) layer(20) and a substrate(10) to be less than 1.5. An amorphous TCO layer is formed on the upper portion of the optical layer. Through heat processing, the amorphous TCO layer is changed into a polycrystal TCO layer. The heating is performed at 120-170°C for 30-120 minutes. An etching process for patterning is performed on the polycrystal TCO layer.
