The second dummy pattern 136D is formed in the opening 136H of the second electrode pattern 136 while keeping a predetermined distance from the second electrode pattern 136 so that the second dummy pattern 136D does not contact the second electrode pattern 136. [ The outer shape of the second electrode pattern 136 may be formed in various shapes such as a triangular shape, a square shape, a diamond shape, a polygonal shape, and a wavy shape.

The first and second dummy patterns 131D and 136D may also be formed of a transparent conductive material such as ITO, IZO, or GZO.

In the touch screen panel according to the present invention, the first connection patterns 110 are formed on a different layer from the first electrode patterns 131, and the neighboring first electrode patterns 131 are formed on the While the second connection patterns 137 are integrally formed without being separated from the second electrode patterns 136. For example, the first connection patterns 110 may be formed integrally with the first electrode patterns 131, and the second connection patterns 137 may be integrally formed with the second electrode patterns 131. However, the present invention is not limited thereto. For example, Patterns 136 may be formed on the other layer to connect the neighboring second electrode patterns 136 to each other.

The routing wiring forming portion B includes a plurality of first routing wirings 112 formed on the outer portion of the electrode forming portion A and connected to the plurality of first electrode rows 130, And a plurality of second routing interconnects 114 each connected to columns 135.

The routing wiring formation portion B may also be configured to further include an insulation layer 120 formed on the first and second routing wirings 112 and 114 to protect the same.

In the embodiment of the present invention, the first and second routing wirings 112 and 114 are formed as a double layer structure, but the present invention is not limited thereto. For example, each of the first and second routing interconnects 112 and 114 may be formed of a single layer of a metal material such as Al, AlNd, Mo, MoTi, Cu, or Cr.

The pad forming portion C includes a plurality of first pads 116 connected to the plurality of first electrode lines 130 via the plurality of first routing interconnections 112, And a plurality of second pads 118 connected to the plurality of second electrode lines 135 through the plurality of first electrode lines 114. Each of the first and second pads 116 and 118 is formed on the first layer 116a or 118a and the first layer 116a or 118a made of a transparent conductive material such as ITO, IZO or GZO A second layer 116b or 118b formed of a metal material such as Al, AlNd, Mo, MoTi, Cu or Cr and a second layer 116b or 118b formed on the second layer 116b or 118b and formed of a transparent conductive material such as ITO, IZO or GZO And a third layer 116c, 118c made of a material.

Although the first and second pads 116 and 118 have been described as having a three-layer structure in the above-described embodiment, the present invention is not limited thereto. For example, the first and second pads 116, 118 may be formed only as a two-layer structure 116a, 116b, 118a, 118b without forming a three-layer structure as the uppermost layer, ) May be formed. However, when the first and second pads 116 and 118 are formed in a three-layer structure, since the uppermost layer is formed of a transparent conductive material such as ITO having high hardness, There is an advantage that it is possible to prevent scratches that may occur in the case of the above.

Meanwhile, in the touch screen panel according to the embodiment of the present invention, the first connection patterns 110, the first and second routing wirings 112 and 114, the first and second pads 110 and 114, And the insulating layer 120 is formed on the substrate 100 on which the insulating layers 120 and 116 are formed.

However, the present invention is not limited thereto. For example, the insulating layer 120 may be formed in the first electrode row 130 so that the first and second electrode rows 130 and 135 do not contact each other in the electrode forming portion A as shown in FIG. 2B But may be partially formed only at the intersection of the first electrode pattern 131a and the second connection pattern 137 constituting the second electrode row 135. [ As the material of the insulating layer 120, silicon nitride (SiNx) is used.

On the insulating layer 120 having the first to fourth contact holes 120a, 120b, 120c and 120d formed thereon, a plurality of first electrode patterns 131 are formed in a first direction (for example, (E.g., a y-axis direction) that is composed of a plurality of second electrode patterns 136 and intersects the first direction, A plurality of second electrode rows 135 are formed.

Since the first electrode patterns 131 constituting the first electrode row 130 are formed separately from each other, they must be connected to each other to form a touch sensing circuit. In the touch screen panel according to the embodiment of the present invention, the first electrode patterns 131 adjacent to each other are formed on the insulating layer 130 exposed through the first and second contact holes 120a and 120b, Are connected to each other by a first connection pattern (110) under the first connection pattern (120). However, the neighboring first electrode patterns 131 may be connected to each other by the first connection pattern 110 exposed through the openings as shown in FIG. 2B.

The first and second electrode patterns 131 and 136 located at the outermost portion of the electrode forming portion A are electrically connected to the first and second routing wirings 112 and 114 through the third contact hole 120c. Respectively. Alternatively, each of the first and second electrode patterns 131 and 136 located at the outermost periphery of the electrode forming portion A may be connected to the first and second routing wirings 112 and 114 through openings, respectively .

The first and second electrode pads 116 and 118 of the pad forming portion C are electrically connected to the first and second routing wirings 120a and 120b through the fourth contact holes 120d as shown in Figs. 112 and 114, respectively.

As described above, in the embodiment of the present invention, the first electrode patterns 131, the second electrode patterns 136, and the second connection patterns 137 using transparent conductive materials such as ITO are formed on the uppermost layer of the touch screen panel Since ITO has a high hardness, scratches do not occur in a subsequent process for forming a display device on the other side of the substrate 100 of the touch screen panel, and a touch screen panel of good quality can be obtained Can be obtained.

Next, the first and second electrode patterns 131 and 136 according to the embodiment of the present invention will be described in more detail with reference to FIGS. 3A to 3D and FIG. 4. FIG.

3A to 3D are plan views showing various shapes of the first and second electrode patterns 131 and 136. FIG 3A is a cross sectional view of the first and second electrode patterns 131 and 136, FIG. 3B is an example of a case where the side shapes of the first and second electrode patterns 131 and 136 are tetragonal, FIG. 3C is an example of the first and second electrode pads 131 and 131, FIG. 3D is a plan view showing an example of a case where the side surface shape of the first and second electrode patterns 131 and 136 is a wavy wave shape, respectively. In the embodiment of the present invention, only four examples of shapes are shown, but the present invention is not limited thereto. For example, the side shapes of the first and second electrode patterns 131 and 136 may be polygonal, parabolic, or a combination of these shapes in addition to the above-described shapes. In other words, any shape can be applied to the present invention as long as the side length is longer than a straight line. Therefore, it should be understood that the shape that can realize the spirit of the present invention is essentially within the protection scope of the present invention.

3A to 3D, since the side surfaces of the first electrode patterns 131 and the second electrode patterns 136 are triangular, tetragonal, trapezoidal, wavy, or the like, Which is much longer than in the case of a straight line. If the lengths of the side surfaces of the first electrode patterns 131 and the second electrode patterns 136 facing each other are increased, the magnitude of mutual capacitance increases when the touch screen panel is driven. Therefore, It is possible to obtain an effect that can be improved.

Each of the first electrode patterns 131 includes a first opening 131H and each of the second electrode patterns 136 includes a second opening 136H. The first dummy patterns 131D are independently formed in the first openings 131H and the second dummy patterns 136D are formed independently in the second openings 136H. When the openings 131H and 136H are formed in the first and second electrode patterns 131 and 136 as described above, since the area of the electrode is reduced, the output data supplied from the source driver and the gate driver The amount of noise due to the change in the voltage level of the output signal is reduced.

Hereinafter, the noise reduction effect by the first and second electrode patterns 131 and 136 according to the embodiment of the present invention will be described in more detail.

FIG. 4 is a plan view for explaining an electrode pattern according to an opening ratio of the openings of the first and second electrode patterns according to the embodiment of the present invention. FIGS. 5A and 5B are cross- 2 is a graph showing the noise voltage and resistance generated in the two-electrode pattern, respectively. In FIG. 4, for the sake of convenience, the shapes of the electrode patterns forming the first and second electrode patterns 131 and 136 are represented by S1, S2, and S3, respectively, and the openings are denoted by H, respectively.

First, three sample electrode patterns (S1, S2, S3) having a size of 20 mm width and 20 mm length as shown in FIG. 4 are prepared for noise voltage and resistance measurement. The three sample electrode patterns S1, S2, and S3 are formed by setting the area of the opening H to 0%, 25%, and 50% of the total area of the electrode patterns S1, S2, and S3. , 25%, and 50%, respectively.

Next, the sample electrodes thus fabricated are formed into first and second electrode patterns of a touch screen panel, respectively, and then the touch screen panel is applied to a display device. After the touch screen panel is driven at 3.3 V, the noise voltage value and the resistance value of the first and second electrode patterns corresponding to the first to third sample electrode patterns S1, S2, and S3 are measured using an oscilloscope . The noise voltage values and the resistance values of the first and second electrode patterns thus measured are shown graphically in Figs. 5A and 5B. In FIG. 5A, the noise voltage value is obtained by first measuring the center area in the state where the active area of the touch screen is divided into nine parts, and measuring the four corner areas later to obtain an average value.

FIG. 5A is a graph showing changes in the noise voltage depending on the aperture ratios of the first and second electrode patterns when the display device is a black gradation and when the gradation is white. In both cases of black gradation and white gradation, It can be seen that the noise voltage gradually decreases as the aperture ratio of the two-electrode pattern increases.

FIG. 5B is a graph showing the resistance change of the first electrode pattern and the second electrode pattern according to the aperture ratio, and shows that the resistance value of the electrode patterns sharply increases when the aperture ratio is about 75% or more.

5A and 5B, it can be seen that as the aperture ratio increases, the noise of the first and second electrode patterns decreases but the resistance increases. Accordingly, it is necessary to appropriately adjust the aperture ratio of the first and second electrode patterns. Considering the noise and resistance of the first and second electrode patterns according to the aperture ratio, the aperture ratio of the first and second electrode patterns is about 40% to about 60%. ≪ / RTI >

As described above, when the first and second electrode patterns 131 and 136 include the openings 131H and 136H, noise generated in the first and second electrode patterns 131 and 136 due to the display device And the effect of reducing the resistance value can be obtained.

However, when the first and second electrode patterns include the openings 131H and 136H, the first connection pattern 110 formed on the lower portion of the insulating layer 120 due to the openings 131H and 136H has visibility . Therefore, it is necessary to solve the problem that the first connection pattern 110 is visible.

6 is a view showing an example in which a dummy pattern is formed in an opening portion of an electrode pattern manufactured in an experimental example in order to solve the visibility problem of the first connection pattern. The sample electrode patterns S1, S2, 5 sample electrode patterns S1, S2, S3, S4 and S5 in which dummy patterns D of 0%, 11%, 22%, 44%, and 64% of the openings H are formed in the openings H, S2, S3, S4, and S5, and FIG. 7 is a graph illustrating a noise value generated in the electrode pattern when the dummy pattern of FIG. 6 is formed.

Noise measurements were made in the same manner as described in connection with Figure 5a. That is, after the first and second electrode patterns are formed with the first sample electrode pattern S1, the touch screen panel is driven at 3.3V. Then, the active area of the touch screen panel is divided into nine equal parts, and the voltage value of the noise is measured by contacting the electrode pattern of the middle area with the probe of the oscilloscope. In this way, the noise values of the four edge regions of the active region are respectively measured, and the noise values of the center regions are summed. When the noise value is calculated, the first and second electrode patterns The first noise value is obtained. The second to fifth noise values of the first and second electrode patterns formed by the second to fifth sample electrode patterns S2, S3, S4, and S5 are obtained in the same manner as described above.

7 is a graph showing changes in noise values of the first and second electrode patterns formed by the first through fifth sample electrode patterns S1, S2, S3, S4, and S5 shown in FIG. In FIG. 7, S1 to S5 represent the noise values of the first and second electrode patterns formed by the first to fifth sample electrode patterns S1, S2, S3, S4, and S5, respectively. 7, the noise value is measured as the smallest value in the absence of the dummy pattern D, but when the dummy pattern D is formed, the size of the dummy pattern D is 22% or more As the size increased, the noise value also decreased. However, if there is no dummy pattern, there is a problem that the first connection pattern 110 is visible. Therefore, in order to satisfy both the visibility problem and the noise problem, it is preferable to set the area of the dummy pattern to be 40% to 70% of the area of the opening.

As described above, according to the embodiment of the present invention, the lengths of the side surfaces of the first electrode patterns facing each other and the side surfaces of the second electrode patterns can be extended to increase the magnitude of mutual capacitance during touch of the touch screen panel Therefore, the effect of improving the touch performance of the touch screen panel can be obtained.

According to the embodiment of the present invention, by forming the openings in the first and second electrode patterns, the voltage level of the output data supplied from the source driver and the gate driver when driving the display device, It is possible to reduce the noise and the resistance value generated in the circuit.
