A liquid crystal display includes a scan line driver (12) to drive scan lines and a power source (14) to supply voltage to the scan line driver. The scan line driver and power source are formed directly on an array substrate of the liquid crystal display. The liquid crystal display also includes a signal-line-driving IC (15) mounted on the array substrate. The IC incorporates a power source (DC voltage converter (1508) and voltage stabilizer (1509)) to supply voltage to a signal line driver (analog output circuit (1504) and the like). The power source in the IC is integrated according to a low-withstanding-voltage manufacturing process. With these configurations, the liquid crystal display is compact and is manufacturable at a low cost.
