In a liquid crystal display device which inputs analogue video signals after phase development, the deterioration of display quality due to the irregularities of circuit can be reduced. To correct the irregularities due to a plurality of analogue circuits, the liquid crystal display device includes look up tables for a plurality of analogue circuits in the inside of a digital signal processing circuit. The liquid crystal display device performs the correction of irregularities of the analogue circuits based on data set in the look up tables.

Liquid crystal display

A projector includes a liquid crystal display device has a liquid crystal display panel and a display control device coupled to the liquid crystal display panel. The display control device is composed of a first section for receiving an externally supplied video signal, and a second section succeeding the first section and coupled to the liquid crystal display panel. The second section is formed of a circuit for amplifying and converting the video signal into an ac signal supplied from the first section, and a drive pulse circuit for outputting drive pulses for driving the liquid crystal display panel. The first section and the second section are fabricated on first and second substrates separate from each other, respectively. The second section is disposed proximately to the liquid crystal display panel, and the first section and the second section are coupled via a flexible cable.

Liquid crystal projector

A liquid crystal display device includes a liquid crystal panel; a plurality of data drivers for applying, to the pixel elements, graduation voltages corresponding to the display data; a gate driver for selecting a pixel element to which a graduation voltage is to be applied; and a liquid crystal control circuit for controlling the data drivers on the basis of a transfer clock. Each data driver includes a reproducing circuit for reproducing the transfer clock input to the data driver such that the deviations between the duties of the display data and the transfer clock input to the data driver and the duties of the display data and the transfer clock output from the data driver become small, and for generating a latch clock, and a latch circuit for latching the display data input to the data driver.
