Zusammenfassung:	A driver circuit-integrated type active matrix substrate 212 has, on a glass substrate 210 , a liquid crystal display unit 221 including a matrix array composed of thin film transistors, and driver circuits 224-226 for driving the liquid crystal display unit. A peripheral portion of the glass substrate 210 has recessed grooves 260-263 formed therein, and power supply lines 251-254 for supplying power to the driver circuits 225 and 226 are 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.
