To provide a display device for a vehicle body which can improve external appearance of a vehicle during non-light emission of a light source arranged in the vehicle body even if the color of the vehicle body is other than dark colors.SOLUTION: A display device for a vehicle body using a front face of the vehicle body as a display panel includes: a light source which is arranged on the front face of the vehicle body and can switch between a light emission state and a non-light emission state; a transmittance variable layer which is arranged at the vehicle outside of the light source and has transmittance to be varied according to an energization state; and a translucent layer which is colored translucent and is arranged at the vehicle outside of the transmittance variable layer. The transmittance variable layer is energization-controlled so that transmittance is increased during light emission of the light source and the transmittance is lowered during non-light emission.SELECTED DRAWING: Figure 1
【課題】車両ボディの色が暗色以外であっても、その車両ボディに配置した光源の非発光時における車両外観上の見栄えを向上させることが可能な車両ボディ用表示装置を提供する。【解決手段】車両ボディの表面を表示パネルとして用いる車両ボディ用表示装置は、車両ボディの表面に配置される、発光状態と非発光状態とが切り替わり可能な光源と、光源よりも車両外側に配置される、通電状態に応じて光の透過率が可変される透過率可変層と、透過率可変層よりも車両外側に配置される、有色半透明な半透明層と、を備える。透過率可変層は、光源の発光時に透過率が上がるようにかつ光源の非発光時に透過率が下がるように通電制御される。【選択図】図1
