Abstract

A liquid crystal display device includes: a light source section; a liquid crystal display panel including pixels and performing video display; and a drive section. The drive section performs the driving on the light source section for turning ON and OFF in synchronization with the driving of the pixels for the light-sequential writing such that, the liquid crystal display panel is selectively illuminated with the light from a lower emission region in the light source section when the pixels in an upper display region are under the driving for line-sequential writing, and such that, the liquid crystal display panel is selectively illuminated with the light from an upper emission region when the pixels in a lower display region are under the driving for line-sequential writing. A phase difference between emission periods in the upper and lower emission regions falls within a range from 90 DEG to 150 DEG both inclusive.

Description

technical field [0001] The present invention relates to a liquid crystal display device that performs video display by dividing an emission area in a light source device such as a backlight. Background technique [0002] In recent years, the demand for thinner displays has been increasing, especially for liquid crystal televisions and PDPs (Plasma Display Panels). Displays for mobile use are often liquid crystal displays, and a high reproducibility of colors with good fidelity is particularly desirable. [0003] In a liquid crystal display device, the liquid crystal element generally undergoes a line-sequential driving operation, that is, a line-sequential writing operation is performed in a vertical direction from the upper end to the lower end of the display screen. The liquid crystal element is an element respectively provided in a plurality of pixels arranged in a matrix. Frames are typically generated at a frame rate of about 30 to 240 Hz. [0004] Also in the liquid...
