Patent ID: 8330896

Claim:
A liquid crystal display device, comprising a liquid crystal display panel and a backlight arranged light to the liquid crystal display panel, wherein the backlight includes a linear light source and a transmittance changing section that is provided between the liquid crystal display panel and the linear light source and arranged to change transmittance of incident light according to where the light is incident; ends of an outer shape of the linear light source are positioned inside a display region of the liquid crystal display panel when the liquid crystal display device is seen from a side where an image is displayed, and the linear light source is positioned to cross at least one of a center line of the display region in a longitudinal direction and a center line of the display region in a horizontal direction; the transmittance changing section is designed such that the transmittance increases as a distance between the transmittance changing section and the linear light source increases; and the transmittance changing section is further designed such that an area positioned outside of the ends of the outer shape of the linear light source in a long side direction has a higher transmittance than an area where the linear light source is positioned.
