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 (40)

1. A display device comprising:

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

a scanning line;

a scanning circuit connected to the scanning line;

a drain line;

a selector disposed at the non-rectangle outer shape and connected to the drain line;

a video signal lead-out line connected to the selector; and

a selector control line connected to the selector, wherein

the selector control line is disposed along the non-rectangle outer shape of the display region,

the selector, and the selector control line are arranged between the display region and the video signal lead-out line,

in a plan view, the scanning line crosses the selector control line and the video signal lead-out line,

the video signal lead-out line includes a first portion, and a second portion which crosses the selector control lines,

the drain line, the selector control line and the first portion are disposed on a first layer, and

the scanning line and the second portion are disposed on a second layer which is different from the first layer.

2. The display device according to claim 1 , wherein

the scanning line is disposed between the selector control line and the selector.

3. The display device according to claim 1 , wherein

the scanning line extends in a first direction in the display region,

the drain line extends in a second direction crossing the first direction in the display region, and

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

4. The display device according to claim 1 , wherein

the scanning line extends in a first direction in the display region,

the drain line extends in a second direction crossing the first direction in the display region, and

the scanning line has a portion extending in the second direction in an outside of the display area.

5. The display device according to claim 4 , wherein

the portion of the scanning line is disposed on the first layer, and

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

6. The display device according to claim 1 , wherein

the selector has a selector TFT, and

the selector TFT has a gate electrode which is connected to the selector control line, and the gate electrode is disposed on the second layer.

7. The display device according to claim 1 , wherein

the drain line is disposed on the first layer.

8. 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.

9. The display device according to claim 1 wherein:

the video signal lead-out line 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.
