ABSTRACT:
The present invention provides a liquid crystal display device which can be used in a miniaturized portable equipment, wherein the liquid crystal display device integrally incorporates a drive circuit therein so that a circuit scale can be miniaturized. A liquid crystal drive circuit includes a first drive circuit and a second drive circuit which is mounted on one side of the liquid crystal display panel. One output of the first drive circuit is connected to a plurality of signal lines and the second drive circuit supplies signals to the first drive circuit. The liquid crystal display panel includes holding capacitive elements and signals are supplied to the holding capacitive elements from the second drive circuit. The second drive circuit includes a booster circuit for supplying signals to the first drive circuit and the holding capacitive elements.
