Embodiment 1

[0058] The sensor portion is formed on a glass substrate by depositing indium tin oxide (ITO). An insulating layer is formed on the sensor part. Molybdenum, argon, nitrogen and carbon dioxide are deposited on the insulating layer by a reactive sputtering process to form a first light absorbing layer. Therefore, the first light absorbing layer includes nitride and oxide. The buffer layer including the first buffer layer, the conductive layer and the second buffer layer is formed by forming a first buffer layer including molybdenum (Mo), a conductive layer including silver (Ag), and a second buffer layer including molybdenum on the first light absorbing layer. Layer connection electrodes.

Embodiment 2

[0060] The touch panel according to the second embodiment was manufactured in the same scheme as in the first embodiment, except that a second light absorbing layer was additionally formed in the same scheme as that of forming the first light absorbing layer on the connection electrodes.

Abstract

Disclosed are a touch panel and a method for manufacturing the same. The touch panel includes a touch panel including a substrate, a sensor part on the substrate and a connection electrode connecting the sensor part, and a light absorbing layer on the substrate. The light absorbing layer is closer to the substrate rather than the connection electrode. The method includes preparing a substrate, forming a sensor part and a connection electrode on the substrate, and forming a light absorbing layer on the substrate. The light absorbing layer is closer to the substrate rather than the connection electrode.

Description

technical field [0001] The present disclosure relates to touch panels and methods for manufacturing the same. Background technique [0002] Recently, a touch panel that performs an input function by touching an image displayed on a display device with an input device such as a stylus pen or a hand has been applied to various electronic devices. [0003] Touch panels can be representatively classified into resistive touch panels and capacitive touch panels. In a resistive touch panel, when pressure is applied to an input device, a position of a touch point is detected by detecting a change in resistance according to a connection between electrodes. In the capacitive touch panel, when a user's finger touches the capacitive touch panel between electrodes, the position of the touch point is detected by detecting a change in capacitance. Recently, capacitive touchpads have been emphasized in smaller models when sensing power and convenience of manufacturing schemes are consider...
