To provide a display unit capable of suppressing variations in luminance of each light source.SOLUTION: A display divider 10 for a vehicle includes a display panel 80 that receives illumination light and emits display light, a plurality of light sources 41a to 41n that emits illumination light and is arranged on a rear side of the display panel 80, a power supply unit 30 that supplies power to the plurality of light sources 41a to 41n, and voltage divider circuits 60a to 60n that apply an output voltage Vd from the power supply unit 30 to the light sources 41a to 41n after lowering the output voltage Vd by an amount of voltage drop corresponding to a luminance difference ΔB such that the luminance difference ΔB due to individual differences among the plurality of light sources 41a to 41n is reduced.SELECTED DRAWING: Figure 1
【課題】各光源の発光輝度のバラツキを抑制することができる表示装置を提供する。【解決手段】車両用表示装置10は、照明光を受けることで表示光を射出する表示パネル80と、照明光を射出し、表示パネル80の背面側に配置される複数の光源41a~41nと、複数の光源41a~41nに電力を供給する電源部30と、複数の光源41a~41nの個体差による輝度差ΔBが小さくなるように電源部30からの出力電圧Vdを輝度差ΔBに応じた電圧降下量だけ降下したうえで光源41a~41nに印加する分圧回路60a~60nと、を備える。【選択図】図1
