Abstract
A driver circuit-integrated type active matrix substratehas, on a glass substrate, a liquid crystal display unitincluding a matrix array composed of thin film transistors, and driver circuitsfor driving the liquid crystal display unit. A peripheral portion of the glass substratehas recessed groovesformed therein, and power supply linesfor supplying power to the driver circuitsandare 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.
