DRIVE CIRCUIT FOR ACTIVE MATRIX LIQUID CRYSTAL DISPLAY

摘要

No drive IC is used in a liquid crystal display, thus the manufacturing cost being low, the step of mounting drive ICs on the array substrate being dispensed with, and the thickness of the liquid crystal display being small. A drive circuit for an active matrix liquid crystal display, which comprises a resistor-division digital-analog converter, the analog output voltage of the converter being amplified by a signal amplifying element and a liquid crystal display element being driven by the amplified analog output voltage, and wherein a resistive element R is formed of a p-Si n<+> layer over the array substrate of the liquid crystal display, and a switching element Tr and the signal amplifying element are formed in the array substrate.
