ABSTRACT:
A television apparatus having a liquid crystal display includes a signal processing portion for reproducing a received video signal, a liquid crystal cell for displaying a video reproduced by the signal processing portion, backlight light sources arranged on a back surface side of the liquid crystal cell for illuminating the liquid crystal cell, drivers for driving the liquid crystal cell, and an inverter for driving the backlight light sources. A transmittance of the liquid crystal cell can be increased because low color-purity cells having a color purity in a range of 40% to 60% is used as the liquid crystal cell. Also, reduction in a color reproductivity of the video caused due to the low color purity can be avoided because a color correcting circuit is provided to the signal processing portion to execute color correcting process on the video signal.
