Abstract

Provided is a liquid crystal display device (1), including: a liquid crystal panel (2); and a backlight unit (4), which is disposed on a rear surface of the liquid crystal panel (2) and includes a light source substrate (42) onto which a plurality of light sources are mounted and a casing (49), in which: the plurality of light sources are arranged along one direction, and at least one of the plurality of light sources is disposed so as to be offset in a direction orthogonal to the one direction with respect to at least another one of the plurality of light sources; and the backlight unit further includes a fixture (50) for fixing the light source substrate (42) onto the casing (49), the fixture being disposed on a side of the offset light source in an opposite direction to an offset direction.

Description

technical field [0001] The invention relates to a liquid crystal display device. Background technique [0002] JP 2007-286627A discloses a liquid crystal display device having a direct type backlight unit. In the liquid crystal display device described above, a plurality of LEDs (Light Emitting Diodes: Light Emitting Diodes) are used as light sources of the backlight unit. The LEDs are arranged in a grid shape over the entire area of ​​the backlight unit. [0003] In the liquid crystal display device described in JP 2007-286627A, since LEDs are arranged over the entire area of ​​the backlight unit, the size of the substrate on which the above-mentioned large number of LEDs are arranged must be set to cover the entire area of ​​the backlight unit. Therefore, not only the cost of preparing a large number of LEDs is high, but also the material cost of the substrate on which the LEDs are placed becomes high. Contents of the invention [0004] The present invention was made ...
