2. Description of the Related Art A touch screen panel is a device that recognizes a user's screen touch or gesture as input information and is widely used in personal portable electronic devices such as a smart phone and a tablet PC. The touch screen panel is mainly used to be disposed adjacent to an apparatus for displaying an image such as a display panel, and a user generally makes a touch input with respect to an image displayed on the display panel.

The touch screen panel generally includes a touch sensing electrode for sensing the user's touch input. Recently, a mesh pattern of a metal material having a low sheet resistance value and high flexibility has been used as a touch sensing electrode. A touch screen panel employing a touch sensing electrode formed of a mesh pattern of a metal material has a structure in which a plurality of X-axis touch cells having a mesh pattern and a plurality of Y-axis touch cells are insulated by a separate insulating layer. That is, in order to electrically isolate the X-axis touch cell and the Y-axis touch cell, a separate insulation layer interposed between the X-axis touch cell and the Y-axis touch cell must be formed. Therefore, The screen panel manufacturing process becomes complicated.

When a plurality of X-axis touch cells having a mesh pattern and a Y-axis touch cell are formed of a metal material, a plurality of X-axis touch cells and a plurality of X- The Y-axis touch cell is visually recognized.

On the other hand, in the case of manufacturing a display device by attaching a separately manufactured touch screen panel to a display panel, it is difficult to increase the thickness of the display device due to the separate substrate used in manufacturing the touch screen panel, And may not be advantageous in terms of design.

A color filter 150 is formed on the first touch sensing electrode 120. 2 and 3 together for a more detailed description of the substrate 110, the first touch sensing electrode 120, the black matrix 130, the second touch sensing electrode 140 and the color filter 150 .

2 is a plan view of the touch screen panel shown in FIG. 3 is a cross-sectional view of the touch screen panel according to III-III 'of FIG. 2, the illustration of the color filter 150 is omitted, the width of the second touch sensing electrode 140 formed on the black matrix 130 is omitted and the first touch sensing electrode 120 are shown by dotted lines.

A plurality of first touch sensing electrodes 120 are formed on the substrate 110. The plurality of first touch sensing electrodes 120 are formed to extend in the first direction. The first touch sensing electrode 120 is formed of a transparent conductive material and may be formed of, for example, indium tin oxide (ITO), graphene, carbon nanotube, or conductive polymer. Although the first touch sensing electrode 120 is shown as a bar in FIG. 1, the first touch sensing electrode 120 may be formed in various shapes extending in the first direction.

A black matrix 130 is formed on the substrate 110 and the first touch sensing electrode 120. That is, a black matrix 130 is formed on the substrate 110 such that the first touch sensing electrode 120 is in contact with the first touch sensing electrode 120, and the first touch sensing electrode The black matrix 130 is formed on the substrate 110 so as to be in contact with the substrate 110.

The black matrix 130 is formed in a mesh pattern.

The plurality of second touch sensing electrodes 140 are formed to extend in the second direction on the black matrix 130. The plurality of second touch sensing electrodes 140 extend in the second direction so that the plurality of second touch sensing electrodes 140 intersect with the plurality of first touch sensing electrodes 120 extending in the first direction . The second direction, which is the extending direction of the plurality of second touch sensing electrodes 140, and the first direction, which is the extending direction of the plurality of first touch sensing electrodes 120, are different from each other. Although the first direction is shown as being perpendicular to the second direction in FIGS. 1 and 2, this is for convenience of description only, and the relationship between the first direction and the second direction is the same as the embodiment shown in FIGS. 1 and 2 .

The second touch sensing electrode 140 is formed of a metal material. Referring to FIG. 2, each of the plurality of second touch sensing electrodes 140 includes a plurality of line patterns 141 formed of a metal material. Since the second touch sensing electrode 140 is formed of a metal material and the second touch sensing electrode 140 is formed outside the touch screen panel 100 due to the high reflectivity of the metal material forming the second touch sensing electrode 140, It can be recognized that a problem such as a moire phenomenon may occur. The second touch sensing electrode 140 is formed on the black matrix 130 in the touch screen panel 100 according to the embodiment of the present invention and the second touch sensing electrode 140 is formed on the outer surface of the touch screen panel 100 In order to prevent the viewer from being viewed. That is, all of the plurality of line patterns 141 of the second touch sensing electrode 140 are formed so as to completely overlap with the mesh pattern of the black matrix 130, and the substrate 110 with the second touch sensing electrode 140 The second touch sensing electrode 140 formed of a metal material is not recognized by the user when the substrate 110 is viewed from the opposite side of the touch sensing electrode 140.

Each of the plurality of second touch sensing electrodes 140 is disposed apart from each other. Accordingly, a spacing space is defined between the plurality of second touch sensing electrodes 140. In Fig. 2, the width of the spacing space is indicated by d. In the touch screen panel 100 according to the embodiment of the present invention, the pitch p of the plurality of second touch sensing electrodes 140 is determined based on a criterion according to a general user's finger size And may be, for example, 3 to 6 mm. The pitch p of the plurality of second touch sensing electrodes 140 is defined as the sum of the width a of the second touch sensing electrode 140 and the width d of the spacing space.

Also, in order to minimize the parasitic capacitance that may occur between the touch sensing electrodes, the width d of the spacing spaces of the plurality of second touch sensing electrodes 140 in the touch screen panel 100 according to an exemplary embodiment of the present invention, Can be set. If the width d of the spacing space of the second touch sensing electrode 140 is too narrow, the parasitic capacitance between the touch sensing electrodes may increase and the touch sensing accuracy of the touch screen panel 100 may deteriorate and malfunction may occur . On the contrary, if the width d of the spacing space of the second touch sensing electrode 140 is excessively wide, that is, if the width d of the spacing space is larger than the size of a general user's finger, . In the touch screen panel 100 according to an exemplary embodiment of the present invention, the width d of the spacing space of the plurality of second touch sensing electrodes 140 can be set for minimizing the parasitic capacitance and for more accurate user touch sensing. For example, the width d of the spacing space may be 3 to 6 mm.

The color filter 150 includes a red color filter 150, a green color filter 150, and a blue color filter 150, which converts the color of light from a display panel attached to the touch screen panel 100 . The red color filter 150, the green color filter 150, and the blue color filter 150 may be formed to correspond to each of the plurality of subpixels defined by the black matrix 130. [

As described above, when the display device is manufactured by separately manufacturing the touch screen panel 100 and the display panel, the thickness of the display device increases due to the use of an additional substrate, which is not advantageous in terms of design . In the touch screen panel 100 according to an embodiment of the present invention, a color filter (not shown) is formed on a substrate 110 having a black matrix 130, a first touch sensing electrode 120 and a second touch sensing electrode 140, 150 are also formed so that the touch screen panel 100 can be integrated with the display panel.

Therefore, since a separate insulating layer is not required to insulate the first touch sensing electrode 120 and the second touch sensing electrode 140, a process for forming a separate insulating layer can be omitted, thereby simplifying the process. have.
