Problems solved by technology

However, a transparent conductive film generally has a high resistance of 150 ohm / □ or more, and thus the sensitivity of a touch panel including the conductive film decreases as the size becomes larger
In addition, the increase in the size of the touch screen leads to a rapid increase in the cost of the ITO film
These issues make commercialization of these touch panels difficult

Embodiment

[0145] After forming an anti-reflection layer (transmittance: 91%, haze: 28%, surface roughness: 0.24 μm) with a dry thickness of 10 μm on PET (125 μm / SKC) by bar coating, it was sputtered on Al is deposited on the anti-reflection layer to provide electrical conductivity, and its thickness is 200 nm. Then, a patterning step is performed to form conductive metal patterns. Figure 5 A conductive metal layer formed by sputtering on a base material and a conductive pattern formed by patterning the conductive metal layer are shown.

[0146] Furthermore, reflection and transmission type diffraction patterns were observed by the same system after forming a touch panel having a GFF type laminated structure. As a result, there was no significant difference in the intensity of the transmission-type diffraction pattern between the comparative example and the example, but in the case of the example, the intensity of the reflection-type diffraction pattern decreased significantly.

Abstract

The present invention relates to a conductive substrate, and to a touch panel comprising same. The conductive substrate according to one embodiment of the present invention comprises: at least one substrate; and at least one conductive pattern provided on the top of the substrate. The conductive pattern has a surface arithmetical mean roughness (Ra) of 0.1 µm to 0.3 µm. The conductive substrate and the touch panel comprising same, according to one embodiment of the present invention, have superior conductivity without blocking a field of view, and also reduce the intensity of a diffraction pattern caused by reflected light.

Description

technical field [0001] This application claims the benefit of Korean Patent Application No. 10-2011-0048170 filed in the Korean Intellectual Property Office on May 20, 2011, the entire contents of which are hereby incorporated by reference. [0002] The invention relates to a conductive substrate and a touch panel comprising the conductive substrate. Background technique [0003] In general, a display device generally refers to a monitor of a television or a computer, etc., and includes a display device for displaying images and a housing for accommodating the display device.
