ABSTRACT:
A driver circuit-integrated type active matrix substrate212has, on a glass substrate210, a liquid crystal display unit221including a matrix array composed of thin film transistors, and driver circuits224–226for driving the liquid crystal display unit. A peripheral portion of the glass substrate210has recessed grooves260–263formed therein, and power supply lines251–254for supplying power to the driver circuits225and226are buried in the recessed grooves. Such a configuration reduces the resistance of bus wiring lines such as the power supply lines for the driver circuits and data lines, without increasing an area of the peripheral portion. The driver circuit-integrated type active matrix substrate reduces an amount of voltage drop in power supply voltage, ensuring reliable operation of the driver circuits.
