Abstract
The present invention allows decreasing the uneven image quality in a liquid crystal display device. The display device in accordance with the present invention includes plural scan signal lines, plural video signal lines, plural TFTs placed in a matrix structure, and plural pixel electrodes, when the width of the scan signal line in a region to place one TFT is different from the width of the scan signal line in a region to place another TFT which is different from the one TFT, the channel width and the channel length of the one TFT is almost equal to the channel width and the channel length of the another TFT, and the surface area of the region overlapping the source electrode with the scan signal line of the one TFT when viewing in plan view is almost equal to the surface area of the region overlapping the source electrode with the scan signal line of the another TFT when viewing in plan view.
