Abstract
The present invention provides a liquid crystal display device which can be used in a miniaturized portable device, wherein the liquid crystal display device has a small area for mounting driving circuits and allows the free mounting of the driving circuits. In the liquid crystal display device having a liquid crystal display element and a liquid crystal driving circuit, the liquid crystal driving circuit is mounted on one side of the liquid crystal display panel. Driving circuits for driving scanning signal lines are provided in plural. The scanning signal line driving circuits sandwich a circuit for driving video signal lines and are arranged in line with the video signal line driving circuit. Lines for transmitting signals to the scanning signal lines are connected to the scanning signal lines from left and right sides of the liquid crystal display panel so as to perform a control of the driving circuits in response to external signals.
