Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel; a video signal control circuit which supplies analog video signals to the liquid crystal; and a driving circuit which is formed above the liquid crystal panel and drives the liquid crystal panel, wherein the video signal control circuit is electrically connected to the liquid crystal panel through a plurality of video signal lines, and includes amplifier circuits which output analog video signals to respective video signal lines, the driving circuit transmits the analog video signals from the video signal control circuit through the plurality of video signal lines to the crystal crystal panel, and the video signal control circuit is formed to phase-develop the digital signals, generate analogue signals from the phased-developed digital signals, amplify the analogue signals, and output amplified analogue signals as the analog video signals from the amplifier circuits, while correcting the irregularities of output among the amplifier circuits by converting values of the phased-developed digital signals.
