Transistor arrays are used for general purpose applications, function generation and low-level, low-noise amplifiers. They include two or more transistors on a common substrate to ensure close parameter matching and thermal tracking, characteristics that are especially important for 'long tailed pair' differential amplifiers, current mirrors, log amplifiers.

The invention provides a transistor array substrate, comprising a thin film transistor, an insulating layer, a flat layer, two electrical testing pins, electrical measuring elements and pixel electrodes, wherein the thin film transistor is arranged on the transistor array substrate; the insulating layer is arranged at the lowest layer of the transistor array substrate; the flat layer is arranged above the insulating layer; the pixel electrodes are distributed above the flat layer; each pixel electrode comprises an upper pixel electrode, a lower pixel electrode and an electrode bridge for connecting the upper pixel electrode with the lower pixel electrode; the electrical measuring elements are arranged at the periphery of the transistor array substrate; the width of parts of electrical measuring elements is same as that of the electrode bridge; and the two electrical testing pins are arranged on the flat layer and connected with two ends of each electrical measuring element respectively. The transistor array substrate can confirm the electrical property of thin film transistor units accurately in time and guide the production condition quickly when any abnormity occurs.
