ABSTRACT:
The present invention aims at acquiring a display device with no brightness irregularities of display. A plurality of drain signal lines are formed in parallel on a pixel-forming-side surface of a substrate. With respect to the respective drain signal lines, a plurality of drain signal lines which are arranged close to each other are formed into each group, and one ends of the respective drain signal lines which are formed into each group are converged together, are extended and are connected to an output terminal of a semiconductor integrated circuit which constitutes a video signal drive circuit. A bus line for supplying reference signals to respective pixels is formed on at least an outer profile side of a mass of pixels at the video signal drive circuit side. The first power supply lines start from both sides of the semiconductor integrated circuit, run outside the drain signal lines which are formed into groups and are connected to the bus line. Second power supply lines start from both sides of the semiconductor integrated circuit, reach portions of the bus line corresponding to an approximately center portion of the drain signal lines which are formed into groups and are connected to the bus line.
