## Abstract

In order to minimize an additional non-output region that is generated when a wire bypasses a non-output region of a display, a mobile terminal is provided which comprises: a display panel including the non-output region; a TFT (Thin Film Transistor) substrate included in the display panel; a TFT wire that is provided on a front surface of the TFT substrate to form an output region and is isolated in the non-output region; a via hole formed at the isolated point of the TFT substrate; and a bypass wire for connecting the isolated TFT wire through the via hole.

## Claims

### Claim 1

A mobile terminal comprising:
a display panel including a non-output region that is contiguous to an output region of the display panel;
a TFT (Thin Film Transistor) substrate included in the display panel;
TFT wires disposed on a front surface of the TFT substrate to define the output region of the display panel,
wherein the TFT wires include isolated TFT wires that have:
first and second TFT wire segments that are isolated from each other by the non-output region, and
third and fourth TFT wire segments that are isolated from each other by the non-output region;
first and second via holes in the TFT substrate corresponding to inner end portions of the first and second TFT wire segments;
third and fourth via holes in the TFT substrate corresponding to inner end portions of the third and fourth TFT wire segments; and
a bypass wire connecting the inner end portions of the first and second TFT wire segments with each other through the first and second via holes while bypassing the non-output region,
wherein the bypass wire includes:
first, second, third and fourth vertical connection wire segments passing through respective ones of the first, second, third and fourth via holes;
a first horizontal connection wire segment connecting ends of the first and second vertical connection wire segments with each other while bypassing the non-output region; and
a second horizontal connection wire segment connecting ends of the third and fourth vertical connection wire segments with each other while bypassing the non-output region,
wherein the first and second horizontal connection wire segments are located in different layers and overlap each other in a thickness direction.

### Claim 2 (depends on 1)

The mobile terminal of claim 1, wherein the first and second horizontal connection wire segments are disposed on a back surface of the TFT substrate.

### Claim 3 (depends on 1)

The mobile terminal of claim 1,
wherein the display panel further includes a lower polarizing plate disposed on a rear surface of the TFT substrate,
wherein the first and second horizontal connection wire segments are disposed on the lower polarizing plate.

### Claim 4 (depends on 1)

The mobile terminal of claim 1, wherein the display panel further includes:
a lower polarizing plate disposed on a rear surface of the TFT substrate; and
an additional layer disposed between the lower polarizing plate and the TFT substrate,
wherein the first and second horizontal connection wire segments are disposed on the additional layer.

### Claim 5 (depends on 1)

The mobile terminal of claim 1, wherein each via hole is defined in a region corresponding to an electrode of the isolated TFT wires.

### Claim 6 (depends on 1)

The mobile terminal of claim 1, wherein the non-output region corresponds to a notch region of a notch display.

### Claim 7 (depends on 1)

The mobile terminal of claim 1, wherein the non-output region corresponds to a sensor hole.

### Claim 8 (depends on 1)

The mobile terminal of claim 1, wherein at least one of the TFT wires is a gate line.

### Claim 9 (depends on 1)

The mobile terminal of claim 1, wherein the non-output region is a circle having a diameter corresponding to a distance between the first and second via holes.
