Abstract

The present invention relates to a touch panel. The touch panel, according to the present invention, comprises: a first transparent substrate divided into an active area and a non-active area locatedaround the active area; a sensing pattern part that includes first sensing cells arranged in the active area of the transparent substrate in the longitudinal direction, a second transparent substrateprovided on the first sensing cells, and second sensing cells arranged on the second transparent substrate in the lateral direction; and first sensing lines and second sensing lines provided in the non-active area of the first transparent substrate to connect the first sensing cells and the second sensing cells to an external driving circuit, respectively, wherein an extended transparent substrateextending from the second transparent substrate along the interconnection wires of the second sensing cells is formed in the non-active area of the first transparent substrate. According to the present invention, among the sensing lines for connecting the sensing pattern having the two-layer structure with the external driving circuit, the sensing lines corresponding to the sensing pattern located on the upper layer are provided on the separate extended upper layer, as opposed to the related art, which makes it possible to omit a separate process for overcoming a step, thereby reducing a metal patterning process and ensuring a competitive price accordingly.

Description

technical field [0001] The present invention relates to a touch panel, and more particularly, to a touch panel including a sensing pattern with a double-layer structure. Background technique [0002] The touch panel is an input device that is included in an image display device or the like and enables user commands to be input by using human hands or objects. For this, a touch panel is provided in front of an image display device, etc., and converts a contact position directly in contact with a human hand or an object into an electric signal so that content selected at the contact position is received as an input signal. Since the touch panel can replace a separate input device such as a keyboard and a mouse connected to an image display device, the range of use of the touch panel is gradually expanding. [0003] As a method of implementing a touch panel, a resistive touch panel, a photosensitive touch panel, and a capacitive touch panel are known. When touched by a human ...
