Fig. 4 is an enlarged view of area A in Fig. 3, and Fig. 5 is an enlarged view of area B in Fig.

The liquid crystal display device 100 according to the embodiment of the present invention includes a gate line GL and a data line DL which are disposed so as to cross each other at the boundary of the pixel region P on the substrate 101, A thin film transistor T connected to the gate line GL and the data line DL and arranged in the pixel region P, a thin film transistor T connected to the data line DL, A first electrode 110 connected to the pixel region P and a second electrode 120 connected to the touch block TB.

At this time, in a display period for displaying an image, a common voltage is supplied to the second electrode 120 to display an image, and in a non-display period in which no image is displayed, the second electrode 120 is touched with a touch It is used as an electrode.

The first electrode 110 is supplied with the data voltage supplied from the data line DL through the thin film transistor T and the second electrode 120 is supplied with the common voltage from the common voltage wiring .

At this time, an electric field is formed by the data voltage supplied to the first electrode 110 and the common voltage supplied to the second electrode 120, and the liquid crystal behaves in accordance with the formed electric field, so that the light emitted from the backlight (not shown) By controlling the transmittance, an image is displayed.

The first and second electrodes 110 and 120 are made of a transparent conductive material such as indium-tin-oxide (ITO) to transmit light emitted from a backlight (not shown) disposed under the substrate 101, Or indium-zinc-oxide (IZO).

The thin film transistor T includes a source electrode S connected to the data line DL, a gate electrode G connected to the gate line GL, and a first electrode And a drain electrode (D) connected to the drain electrode (110).

The first electrode 110 is in the form of a flat plate and the second electrode 120 is connected to the first electrode 110 and the data line DL to form a plurality of bar- A connecting portion 123 connected to both ends 121a of the finger 121 and a disconnecting portion 125 for disconnecting the connecting portion 123 at each touch block TB boundary.

At this time, the fingers 121 overlapping the data lines DL have a width larger than the fingers 121 overlapping the first electrodes 110.

Also, the connection part 123 of the second electrode 120 may partially overlap with the gate line GL to form a storage capacitor.

The fingers 121 are symmetrical with respect to the central portion of the pixel region P and are bent at a first angle.

Accordingly, one pixel region P is divided into two domains with respect to the central portion of the pixel region P, whereby the liquid crystals can be driven differently within the respective domains, and the light transmittance along the viewing angle direction And can be uniform.

The fingers 121 of the second electrode 120 are bent at a second angle? 2 larger than the first angle? 1 at the central portion of the pixel region P, Can be prevented.

Also, both ends 121a of the fingers 121 of the second electrode 120 are also bent at a second angle? 2, wherein the second angle? 2 is preferably 45 degrees.

This minimizes the difference in the directions in which the liquid crystal molecules located at the both ends 121a of the fingers 121 are minimized to minimize the formation of discontinuous domains, The disclination phenomenon can be prevented.

On the other hand, the data line DL is bent at the central portion of the pixel region P in the same manner as the fingering pattern 121.

In addition, both ends of the break part 125 of the second electrode 120 may be formed in a straight line shape. Light leakage may occur in the break part 125.

That is, the connection part 123 and the disconnect part 125 of the second electrode 120 are partially overlapped with the gate line GL, and the connection part 123 of the second electrode 120 forming the disconnection part 125, A light leakage phenomenon may occur in the broken portion 125 by driving liquid crystal molecules located in the broken portion 125 even in a black state by the electric field formed by the step and the gate wiring GL.

In order to prevent the delay of the touch signal supplied to the sensing circuit (not shown), the touch wiring TL is preferably made of a low resistance metal material such as Al and Cu, and may be formed as a single layer or a double layer.

At this time, the shielding pattern 150 is also formed of the same material and the same layer as the touch wiring TL.

The shielding pattern 150 may have the same width as the connection portion 123 of the second electrode 120 or may have a width larger than the connection portion 123 of the second electrode 120. However, It is preferable that the second electrode 120 has the same width as the connection portion 123 of the second electrode 120.

The shielding pattern 150 may overlap the connection portions 123 on both sides of the disconnected portion 125 of the second electrode 120. Accordingly, the shielding pattern 150 can be completely overlapped with the disconnected portion 125 of the second electrode 120. [

Accordingly, although the second electrode 120 is disconnected by the disconnecting part 125, the connection part 123 of the second electrode 120 disconnected by the disconnection part 125 in a plan view by the shielding pattern 150 ) Appears to be connected.

As described above, the touch wiring TL is electrically connected to the second electrode 120, one for each touch block TB. At this time, the second electrode 120 is connected to the common voltage wiring (not shown) And the common voltage is supplied through the common terminal.

Since the shield pattern 150 is formed extending from one side of the touch wiring TL and the touch wiring TL is connected to the second electrode 120 through the touch contact hole (TCH in FIG. 3) And a common voltage is supplied through a common voltage wiring (not shown)

Since the second electrode 120 and the shielding pattern 150 are both supplied with the common voltage from the common voltage wiring (not shown), the disconnection of the second electrode 120 located at the boundary of the touch block TB 125 and the connection portion 123 of the second electrode 120 are formed in the same direction.

That is, the shielding pattern 150 is formed between the both ends of the connection part 123 of the second electrode 120 disconnected by the disconnection part 125 of the second electrode 120 and the electric field The liquid crystal molecules located in the disconnection part 125 and the liquid crystal molecules located in the connection part 123 can have the same direction of response.

As a result, the liquid crystal molecules located in the disconnection part 125 are not driven in the black state, and the light leakage phenomenon in the disconnection part 125 can be prevented.

In addition, it is not necessary to form a separate black matrix (not shown) in the single wire portion 125 in order to prevent the light leakage phenomenon and to improve the display quality, The manufacturing cost can be reduced.
