摘要： A backlight unit has a light source area. The width of the light source area in a first direction is shorter than the width of a liquid crystal panel in the first direction. A plurality of LED modules (31) are arranged along the second direction perpendicular to the first direction. End lenses (41A, 41B) and a middle lens (42) for enlarging a light divergence angle are disposed on the plurality of LED modules (31). The direction in which the end lens (41A, 41B) enlarges the light divergence angle differs from that in which the middle lens (42) enlarges the divergence angle. This structure can reduce difference in brightness of the liquid crystal panel, while reducing the number of light sources.

摘要： The present invention provides a display method realizing reduction in a moving picture blurring by forming one frame by two fields of different luminance, in which increase in an unapplied voltage due to shortening of data voltage write time is suppressed. A gate voltage is applied in a light field for a period of time which is twice as long as scan line selection time, thereby decreasing an unapplied voltage. On the other hand, a gate voltage is applied normally in a dark field for the scan line selection time, so that the case where the unapplied voltage increases is eliminated. As a result, an image with high reproducibility can be obtained.
