Abstract
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.
