And a backlight unit 206 are stacked in this order. In this case, the TFT (Thin Film Transistor), which is referred to as the wiring 250 in the present invention, may be provided on the entire surface of the TFT substrate 241.

In order to solve the conventional disadvantage, the present invention proposes a form in which the wiring 250 penetrates and is connected in the thickness direction of the display panel 201. This is distinguished from detouring on the entire surface of the TFT substrate 241 as shown in FIG.

In other words, the present invention bypasses the rear specific layer rather than the front of the TFT substrate 241.

For convenience of description, the wiring 250 provided on the front surface of the TFT substrate 241 is bypassed with the TFT wiring 251 and the wiring 250 connecting the TFT wiring 251 disconnected due to the non-output region 210. This is defined as the wiring 252.

The TFT wiring 251 is provided on the entire surface of the TFT substrate 241 to form an output region. The TFT wiring 251 is disconnected in the non-output region 210.

The TFT substrate 241 is provided with the via hole 245 at the disconnection point of the TFT wiring 251. The via hole 245 may be formed in the thickness direction of the TFT substrate 241 to the rear of the TFT substrate 241. For example, the via hole 245 may be formed vertically downward of the TFT substrate 241. Since the TFT wiring 251 is disconnected at two points due to the non-output region 210, the via hole 245 is formed at two points at which it is disconnected.

As a result, the position of the via hole 245 determines the size of the non-output region 210. The via hole 245 may be provided as close as possible to the hole 243 forming the non-output area 210. When provided as close as possible to the hole 243, the TFT wiring 251 may be provided at the maximum, thereby maximizing the output area.

The bypass wiring 252 connects the disconnected TFT wiring 251 through the via hole 245. The bypass wiring 252 may be provided with the same material and the same thickness as the TFT wiring 251.

In this case, the via hole 245 is not exposed to the hole 243. The bypass line 252 should be provided through the via hole 245 because the bypass line 252 may be exposed to the outside when the via hole 245 is formed to be exposed to the hole 243.

For this reason, the via hole 245 is provided at a specific distance G from the hole 243. As a result, the non-output region 210 is the sum of the diameter of the hole 243 and the spaced distance G.

When the via holes 245 at two points are provided in the thickness direction of the display panel 201, the bypass wires 252 passing through the via holes 245 are formed in the vertical connection wires 2521 and the vertical connection wires 2521. The bypass wiring 252 connecting the ends is called a horizontal connection wiring 2522.

The length of the horizontal connection line 2522 corresponds to the diameter of the non-output region 210. However, since the horizontal connection line 2522 does not directly participate in the size of the non-output area 210, it may be provided in a relatively free form.

The via hole 245 may coincide with the position of the electrode 2511 of the TFT wiring 251.

Depending on the depth at which the via hole 245 is formed, the layer in which the horizontal connection wiring 2522 is provided among the display panels 201 is different.

6 to 8 illustrate the embodiment of FIG. 5 in more detail, and show embodiments according to a position where the horizontal connection line 2522 is provided.

6 is an embodiment of a mobile terminal 100 according to the present invention.

The horizontal connection wiring 2522 of the bypass wiring 252 may be provided on the TFT substrate 241. The horizontal connection wiring 2522 may be provided through the inside of the TFT substrate 241 or may be provided on the rear surface of the TFT substrate 241.

7 is an embodiment of a mobile terminal 100 according to the present invention.

The horizontal connection wiring 2522 of the bypass wiring 252 may be provided in the lower polarizing plate 205 provided under the TFT substrate 241.

8 is an embodiment of a mobile terminal 100 according to the present invention.

The horizontal connection wiring 2522 of the bypass wiring 252 may be provided in the additional layer 207 provided between the TFT substrate 241 and the lower polarizer 205.

9 is an embodiment of a mobile terminal 100 according to the present invention.

Although FIG. 9 illustrates the premise of the gate line 250a provided in the left and right directions, this may be generalized to the wiring 250. Therefore, it may be applied to the up and down direction within the range that does not contradict, and may be applied to the data line 250b.

Unlike the above embodiments, the output area disconnected due to the non-output area 210 may be divided and connected by a gate in panel (GIP) additionally provided.

That is, if the first GIP 261 is provided at one side of the N region, which is an area of the display panel 201 without the non-output region 210, and the fourth GIP 264 is provided at the other side, the wiring is connected to each other. In the area Y of the display panel 201 where the non-output area 210 is located, a second GIP 262 is provided on one side of the non-output area 210 and a third GIP 263 is provided on the other side. The first GIP 261 and the second GIP 262 are connected to each other by the wiring 250, and the third GIP 263 and the fourth GIP 264 are connected to each other by the wiring 250.

This embodiment does not need to have a separate wiring 250 structure bypassing the non-output region 210 due to the addition of the second GIP 262 and the third GIP 263, and thus the non-output region 210. The size of can be minimized.

One GIP control signal is applied to the first GIP 261 and the second GIP 262, and the other GIP control signal is applied to the third GIP 263 and the fourth GIP 264. To this end, the first GIP 261 and the second GIP 262 are connected to the same control signal line 272, and the third GIP 263 and the fourth GIP 264 are also connected to the same control signal line. The GIP driver 271 may apply a control signal to each GIP.

Unlike the control signal, the voltage may be connected to different GIPs. That is, one voltage line 273 may be connected to the first GIP 261 and the third GIP 263, and the other voltage line 274 may be connected to the second GIP 262 and the fourth GIP 264. have. This can prevent the image quality deterioration due to the difference between the voltage on one side and the voltage on the other side.

It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
