Abstract

A liquid crystal display device having an outer shape of a display region formed other than a rectangle. A driver for supplying a video signal is disposed outside the display region. A selector with selector TFT is disposed between the display region and the driver. A video signal line is disposed between the driver and the selector, and a drain line is disposed between the selector and the display region. A scanning circuit for supplying a scanning signal to the scanning line is disposed outside the display region. The selector is disposed between the scanning line and the display region, and covered with ITO as the common electrode. The common bus wiring is disposed outside the selector.

Claims (33)

1. A display device comprising:

a substrate having a display region having a non-rectangle outer shape and a peripheral region;

a first wiring extending in a first direction in the display region,

a second wiring extending in a second direction crossing the first direction in the display region;

a transistor disposed at the peripheral region and connected to the second wiring;

a lead wiring connected to the transistor; and

a transistor control wiring connected to the transistor, wherein

the transistor control wiring is disposed along the non-rectangle outer shape of the display region,

the transistor and the transistor control wiring are disposed between the display region and the lead wiring,

the first wiring crosses the transistor control wiring and the lead wiring at the peripheral region,

the first wiring has a portion which extends in the second direction between the display region and the transistor control wiring,

the transistor control wiring is disposed on a first layer,

the lead wiring includes a first portion which is disposed on the first layer, and a second portion which crosses the transistor control wiring and is disposed on a second layer which is different from the first layer, and

the transistor has a gate electrode which is connected to the transistor control wiring, and the gate electrode is disposed on the second layer.

2. The display device according to claim 1 , wherein

the transistor control wiring extends in the first direction and bend to the second direction along the outer shape of the display region.

3. The display device according to claim 1 , wherein

the portion of the first wiring is disposed on the first layer, and

the first wiring other than the portion of the scanning line is disposed on the second layer.

4. The display device according to claim 1 , wherein

the second wiring is disposed on the first layer.

5. The display device according to claim 1 , further comprising an insulation layer disposed between the first layer and the second layer,

wherein the second layer is disposed between the insulation layer and the substrate.

6. The display device according to claim 1 further comprising: a scanning circuit connected to the first line,

wherein

the lead wiring is connected to a driver IC,

the outer shape of the display region is formed by combining a linear part and a curved part,

the driver IC is disposed corresponding to the linear part, and

the scanning circuit is disposed corresponding the curved part.

7. The display device according to claim 1 wherein

the portion of the first wiring does not cross the transistor control wiring and the lead wiring in a plan view.

8. The display device according to claim 1 wherein

the portion of the first wiring is disposed between the transistor and the transistor control wiring.
