To provide an optical device for vehicle excellent in visibility.SOLUTION: An optical device 100 for vehicle includes a light irradiation part 300 that has partition parts 130 which are partitioned into a plurality of parts and can be turned on/off, and irradiates the outside of the vehicle with light in lighting, and a louver 110 which is provided along a front surface of the light irradiation part 300, is arranged on at least an upper side of the partition parts 130 and acts as a light-shielding member. Accordingly, the light irradiation part 300 allows the louver 110 to block direct lighting of sun light in the partition parts 130 and can achieve appearance (display) with high contract by a brightness difference. The louver 110 can make a shadow on the partition parts 130, which can suppress brightness in daytime of the light irradiation part 300 and achieves reduction in power consumption.SELECTED DRAWING: Figure 1
