Patent ID: 7982709

Claim:
A liquid crystal display device comprising: a liquid crystal panel having a pair of substrates, a liquid crystal layer sandwiched between said paired substrates, data lines for applying to said liquid crystal layer a voltage corresponding to image data at a predetermined timing and gate lines, a plurality of active elements connected to intersections of said data lines and said gate lines and pixels driven by said active elements; and an illuminating device having a plurality of LED packages each including LED's and a lens, said LED packages being congregated on a plane in a large area to provide a backlight for irradiating light to said liquid crystal panel, wherein, on a plane substantially parallel to said liquid crystal panel, denoted as a column direction is a direction substantially parallel to a direction in which the gate line extends and denoted as a row direction is a direction substantially orthogonal to the column direction, the bottom of said backlight having the congregated LED packages being divided into two or more plural regions, and there is provided means for driving the LED's individually or in respect of each of said plurality of regions and said lens in each of said LED packages has different widths between in the column and row directions.
