Zusammenfassung:To provide a vehicle display device that can cause a light-emitting portion to appropriately emit light.SOLUTION: A vehicle display device 1 comprises: plate-like members 13 that each have exposure holes 20 provided penetrating along the axial direction X in a light-shielding area 19; a light source 15 that is located separated from a rotation axis of a pointer with respect to the exposure holes 20 and emits light having a visible light area component; a light guide body 16 having protrusive graduations 9 that are provided protruding through the exposure holes 20, an incident surface 23 that is located opposite to the light source 15 along the axial direction X and on which the light emitted from the light source 15 is made incident, and a light guide part 24 that guides the light made incident on the incident surface 23 to the protrusive graduations 9; and a first light-shielding wall part 17 that is located between the light source 15 and incident surface 23 with respect to the axial direction X and located between the light source 15 and exposure holes 20 with respect to a direction intersecting the axial direction X, and blocks leakage light that is emitted from the light source 15, not made incident on the incident surface 23, and directed toward the exposure holes 20.SELECTED DRAWING: Figure 2 【課題】発光部位を適正に発光させることができる車両表示装置を提供することを目的とする。【解決手段】車両表示装置1は、遮光領域19内に軸線方向Xに沿って貫通して設けられた露出孔20を有する板状部材13と、露出孔20より指針の回動軸線から離間して位置し可視光域成分の光を照射する光源15と、露出孔20を介して突出して設けられる突状目盛9、軸線方向Xに沿って光源15と対向して位置し光源15から照射された光が入射される入射面23、及び、入射面23に入射された光を突状目盛9に導光する導光部24を有する導光体16と、軸線方向Xに対して光源15と入射面23との間に位置すると共に軸線方向Xと交差する方向に対して光源15と露出孔20との間に位置し、光源15から照射され入射面23に入射せず露出孔20側に向かう漏れ光を遮光する第1遮光壁部17とを備える。【選択図】図2
