Patent ID: 7034810

Claim:
A liquid crystal display device comprising a liquid crystal display element having a plurality of pixels and a plurality of image signal lines for applying a gradation/tone voltage corresponding to display data to said plurality of pixels, and an image signal line drive unit for supplying to each image signal line a gradation/tone voltage corresponding to display data, wherein: said image signal line drive unit has a plurality of semiconductor integrated circuit devices, each semiconductor integrated circuit device has an input circuit unit as provided in a short side direction of said semiconductor integrated circuit device, a first output terminal section provided on both sides of said input circuit unit in a longitudinal direction of said semiconductor integrated circuit device and also provided in the longitudinal direction of said semiconductor integrated circuit device, and a pair of output circuit units provided on both sides of said first output terminal section in the short side direction of said semiconductor integrated circuit device for generating a gradation/tone voltage to be supplied to each image signal line, wherein said pair of output circuit units are such that a positive polarity output circuit unit for generation of a positive gradation/tone voltage and a negative polarity output circuit unit for generation of a negative gradation/tone voltage are provided alternately.
