To provide a vehicular
display device that can intuitively inform a driver of a degree of a risk that a vehicle may deviate from a travelling lane.SOLUTION: A vehicular
display device 10 comprises: a pair of left and right light emitting parts 34 (a left-side light emitting part 30A and a right-side light emitting part 32A), arranged in a vehicle interior 14, which are configured so that light can visually observed, at a side closer to inside than a pair of left and right
road surface lines M (a road-side belt DL and a lane-change line RM) on a travel lane DL and in a direction which extends in a nearly same direction as respective directions of the pair of left and right
road surface lines M; and a display part that when a vehicle 12 tries to deviate from the travel lane DL, changes at least either of a cycle of flashing of the light emitting part (the right-side light emitting part 32A) at the lane side which the vehicle tries to deviate from and a movement
speed of light that is emitted flowingly from the light emitting part (the right-side light emitting part 32A), in accordance with a degree of a risk that the vehicle may deviate, and displays the degree.SELECTED DRAWING: Figure 1
