Liquid crystal display device
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.
1. A display device comprising:
a display region, which includes plural pixels, having a non-rectangle outer shape;
a peripheral region around the display region;
a substrate having scanning lines, drain lines, and pixel electrodes; and
a scanning circuit connected to the scanning lines,
wherein
the scanning lines, extending in a first direction and arranged in a second direction that intersects the first direction, have a first scanning line and a second scanning line,
the drain lines, extending in the second direction and arranged in the first direction, have a first drain line and a second drain line,
the pixel electrodes have a first pixel electrode in the display region and a second pixel electrode in the peripheral region,
the second scanning line has a first portion extending the second direction in the peripheral region, a second portion extending the first direction in the display region, and a third portion extending the first direction in the peripheral region,
the first portion of the second scanning line connects the second portion of the second scanning line and the third portion of the second scanning line,
the first pixel electrode is surrounded by the first scanning line, the second portion of the second scanning line, the first drain line and the second drain line in a plan view, and
the second pixel electrode overlaps with the first portion of the second scanning line in a plan view.
2. The display device according to claim 1 , further comprising a first video signal lead-out line provided in the peripheral region,
wherein
the first video signal lead-out line is connected to the first drain line via a selector, and
one of the first scanning line and the second scanning line crosses the first video signal lead-out line in the peripheral region.
3. The display device according to claim 2 , wherein
the selector has a selector thin film transistor,
a gate of the selector thin film transistor is connected to a selector control line, and
the selector control line is in a same layer as the drain lines.
4. The display device according to claim 1 , wherein
the second pixel electrode is a dummy pixel electrode.
5. The display device according to claim 3 , wherein
the second pixel electrode overlaps with the selector control line in a plan view.
6. The display device according to claim 2 , wherein
the second pixel electrode overlaps with the first video signal lead-out line in a plan view.
7. The display device according to claim 3 , wherein
the selector control line crosses one of the first scanning line and the second scanning line via an insulation film in a plan view, and
the selector control line crosses the first video signal lead-out line via the insulation film in a plan view.
8. The display device according to claim 1 , wherein
the second pixel electrode is supplied with a common voltage.
