Abstract: The present invention provides a liquid crystal display capable of making the variations and the oblique lines, which are caused on the screen in the liquid crystal display using the TN liquid crystal panel, less visible. The liquid crystal display includes a video signal reception section adapted to receive a video signal, a signal input detection section adapted to detect presence or absence of the video signal, a luminance control section adapted to control the luminance of the backlight, and a control section adapted to instruct the luminance control section to reduce the luminance of the backlight as a predetermined amount in the case in which the signal input detection section fails to detect the video signal.

Abstract: An audio signal is transmitted to a sensor substrate D through a cable 60c connecting the lower end of an analog substrate A arranged on the rear face of the liquid crystal panel and the sensor substrate arranged below the liquid crystal panel of a cabinet. The cable 60c is covered with UL tube in advance, and connected by being passed through the inside of a horseshoe shape of a lower bridge pier portion 52b3 of the right bridge frame 52b. The audio signal is transmitted to the speakers 53a, 53b connected to the connectors 61a, 61b with lead wires by the pattern on the sensor substrate D.
