FIELD: electricity.
SUBSTANCE: back light unit (49) for display device (69) equipped with LCD panel (59) contains a frame (41), dissipating plate (43) supported by the frame and point light sources supported by mounting substrates (21) provided at the frame. Point light sources contain LEDs (22) installed at mounting substrates. Mounting substrates (21) are interconnected by connectors (25) thus forming rows (26) of mounting substrates (21). Varieties of rows (26) of mounting substrates (21) are located in parallel; a row (26) of mounting substrates (21) is formed by long and short mounting substrates (21) and location of such long and short mounting substrates (21) is changed to the opposite row-by-row. Positions of connectors (25) are not levelled in a straight line in direction of rows (26) of mounting substrates (21).
EFFECT: providing uniform brightness of the dissipating plate.
