A resistance value of the first conductive member in the third direction changes. A resistivity of the second conductive member in the second direction is lower than a resistivity of the second conductive member in the third direction.

    • 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.
    • 具有液晶显示器的电视装置包括用于再现接收的视频信号的信号处理部分,用于显示由信号处理部分再现的视频的液晶单元,布置在液晶单元的背面侧的背光源 照射液晶单元,用于驱动液晶单元的驱动器和用于驱动背光光源的逆变器。 液晶单元的透光率可以提高,因为使用色纯度在40%〜60%范围内的低色纯度单元作为液晶单元。 此外,由于向信号处理部分提供了颜色校正电路以对视频信号执行颜色校正处理,因此可以避免由于低色纯度导致的视频的颜色再现性的降低。
