Embodiment 1

[0041] figure 2 It is an example of a special-shaped display panel. figure 2 In , both the display area 1000 and the outer shape are formed in a racetrack shape with straight lines up and down and curved sides. figure 2 It is a top view of the TFT substrate side. figure 2 In the display area 1000 , the scan lines 10 extend in the horizontal direction, the drain lines 20 extend in the vertical direction, and pixels are formed in the area surrounded by the scan lines 10 and the drain lines 20 .

[0042] figure 2 In the display area 1000, the selector 30 and the driver IC 40 are arranged on the lower side. The outside of the driver IC 40 serves as a terminal region 150 for connection to the flexible wiring board. A video signal is supplied from the driver IC 40 to the drain line 20 of the display region 1000 via the selector 30 . There are drain lines 20 as many as horizontal pixels in the display region 1000 , but the number of video signal lead-out lines 21 from the d...

Abstract

The invention provides a display device configured to have the display region with reduced frame area in spite of the variant-shape display panel with the variant-shape display region including the selector circuit. A liquid crystal display device having an outer shape of a display region formed other than a rectangle is disclosed in the invention. A driver 40 for supplying a video signal is disposed outside the display region 1000. A selector 30 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 20 is disposed between the selector and the display region. A scanning circuit 11 for supplying a scanning signal to the scanning line 10 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.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device whose display area and shape are not rectangular. Background technique [0002] In a liquid crystal display device, which is one of display devices, a TFT substrate having pixel electrodes, thin film transistors (TFTs) and the like and pixels formed in a matrix is ​​arranged, and an opposing substrate facing the TFT substrate, and the TFT substrate and the opposing substrate Liquid crystals are sandwiched between them. Then, an image is formed by controlling the transmittance of light based on liquid crystal molecules for each pixel. Liquid crystal display devices are flat and lightweight, and thus are widely used in various fields. [0003] In liquid crystal display devices, the display area or shape is often rectangular, but in display devices used in automobiles, display devices used in various games, etc., display devices whose display area or shape is not rectan...
