Is formed only on the lower side, and it is not necessary to form a separate second routing wiring region on the left and right sides of the touch area TA.

Therefore, the effect of saving the bezel area on the left and right sides can be obtained as compared with the conventional art.

It will be appreciated that various changes and modifications can be made by those skilled in the art through the above description without departing from the technical spirit of the present invention.

For example, in the first to fourth embodiments of the present invention, the touch driving electrode is formed on the substrate, and the touch sensing electrode is formed on the insulating film covering the touch driving electrode. It is of course possible to form the touch sensing electrode and to form the touch driving electrode on the insulating film covering the touch sensing electrode.

In addition, in the first to fourth embodiments of the present invention, the touch driving electrodes and the touch sensing electrodes, the routing lines are described as being formed on the substrate and the insulating layer covering the substrate. It is of course possible to form and implement touch driving electrodes, touch sensing electrodes, and routing lines on the lower surface thereof.

In addition, in the touch screen panel according to the exemplary embodiment of the present invention, the touch driving electrodes and the touch sensing electrodes are formed with the insulating layer interposed therebetween, or are formed on both surfaces of one substrate to be formed on different layers. However, the present invention is not limited thereto. For example, when the insulating pattern is formed only at the intersection of the touch driving electrode and the touch sensing electrode, the touch driving electrode and the touch sensing electrode may be formed on the same layer. In this case, since the touch sensing electrode and the touch driving electrode are formed on the same layer, the visibility may be improved.

In addition, although the touch driving electrodes have a block shape and the touch sensing electrode has a bar shape in the first to fourth embodiments of the present invention, the shapes of the touch electrodes may have various shapes. In particular, if the intersection of the touch driving electrode and the touch sensing electrode is narrowly formed, the size of the mutual capacitance formed between the touch driving electrode and the touch sensing electrode can be increased, thereby improving the touch precision.

An example of changing the shapes of the touch electrodes (touch driving electrode and touch sensing electrode) will be described with reference to FIGS. 14A and 14B. 14A illustrates an example in which the first touch electrodes (eg, the touch driving electrodes Tx1 and Tx2) have an H shape, and the second touch electrodes (eg, the touch sensing electrode Rx1) have a bar shape. 14B shows a first touch electrode (for example, a touch driving electrode, Tx1, and Tx2) having an elongated shape, and a second diamond electrode (eg, a touch sensing electrode, Rx1) has a continuous rhombus shape. It is a top view which shows the example which has a connected shape. As shown in FIGS. 14A and 14B, an area where the first and second touch electrodes intersect is narrower than another area. Therefore, according to the structure of FIGS. 14A and 16B, since the overlapping area of the first touch electrodes Tx1 and Tx2 and the second touch electrode Rx is reduced, the change in capacitance during touch can be increased, so that the touch The precision can be improved.

Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
