Abstract: A vehicle video display device is installed on the armrest of a vehicle. Two arm members have one of their ends pivotally attached to two opposite surfaces of the armrest so that the two arm members extend outward from the armrest in parallel. A beam member has its two ends rotatably joined to the other ends of the two arm members respectively so that the beam member is supported across the armrest. A screen member is positioned rotatably on the beam member by an axle.
