    • A backlight unit comprises a circuit board (20) having, a plurality of LED's (22) arranged in a matrix, a diffuser panel (62), and a support pin (50) positioned between the circuit board (20) and the diffuser panel (62) for supporting the diffuser panel (62). The support pin (50) includes a first fixation portion (51) inserted in a hole (21) formed on the circuit board (20), a second fixation portion (52) positioned apart from the first fixation portion (51), and a pillar (53) having a tip end supporting the diffuser panel (62). The pillar (53) and the first fixation portion (51) are aligned in a direction perpendicular to the circuit board (20). According to this backlight unit, it is possible to ensure freedom in wiring around the LED's (22) and to prevent the pillar (53) of the support pin (50) from hindering the light.
    • 一种背光单元包括具有多个以矩阵形式布置的LED(22)的电路板(20),扩散板(62)和位于电路板(20)和扩散板之间的支撑销(50) (62),用于支撑扩散板(62)。 支撑销(50)包括插入形成在电路板(20)上的孔(21)中的第一固定部分(51),与第一固定部分(51)分离的第二固定部分(52) 支柱(53)具有支撑扩散板(62)的顶端。 支柱(53)和第一固定部分(51)在垂直于电路板(20)的方向上排列。 根据该背光单元,能够确保LED(22)周围的配线的自由度,并且防止支撑销(50)的支柱(53)阻碍光。
