Abstract
A display device includes a first substrate having formed thereon a plurality of video signal lines and a plurality of gate signal lines, a plurality of pixel electrodes, a plurality of thin film transistors, and a plurality of pixels. Each pixel includes a pixel electrode of the plurality of pixel electrodes and a thin film transistor of the plurality of thin film transistors. The thin film transistor includes a semiconductor layer, a drain electrode electrically connected to a drain signal line, and a source electrode electrically connected to the pixel electrode. The semiconductor layer has an outline so that a nearest portion to a center of the pixel is positioned under the source electrode in plan view.
