A display device that can prevent linear unevenness (uneven line) generated in one direction of a display image and can provide excellent display qualities includes a pixel including sub-pixels of n-colors (where n is an integer of 4 or more), and a signal line arranged to drive sub-pixels, the pixel and the signal line arranged to drive sub-pixels being disposed in a display region. The signal line arranged to drive sub-pixels is disposed on a display region center side of a sub-pixel positioned at least one terminal of the display region. The signal line arranged to drive sub-pixels is not disposed on a non-display region side of the sub-pixel positioned at the at least one terminal. The sub-pixel positioned at the at least one terminal has a color other than a color with the highest luminance of the n-colors.

Display device

An active matrix substrate of the present invention includes a TFT and a substrate. The TFT formed on a substrate includes, when viewed in a normal direction of the substrate: a first region in which a gate electrode overlaps a source electrode via a semiconductor layer; a second region in which the gate electrode overlaps a drain electrode via the semiconductor layer; and a third region in which the semiconductor layer overlaps neither the gate electrode, source electrode, nor the drain electrode. The third region includes a portion adjoining the source electrode lying outside the first region and/or a portion adjoining the drain electrode lying outside the second region. The gate electrode includes: a main body, which includes a portion constituting the first region and the second region; and a protrusion from the main body. At least a part of the protrusion of the gate electrode is in between the drain electrode and the portion of the third region adjoining the source electrode, or between the source electrode and the portion of the third region adjoining the drain electrode.
