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.
