US Patent 8622354 Display

A display includes: a display section; and a supporting section including a post and a base and supporting the display section. The post includes: a tubular upper post extending in a direction perpendicular to a horizontal plane; a tubular lower post separated from the upper post at a separating plane tilted with respect to the horizontal plane and having a variable mounting angle with respect to the upper post by rotating around a central line of the upper post on the separating plane; and a tilt mechanism disposed on a side opposite to the separating plane of the upper post and changing a tilt angle in an elevation direction of the display section. A tilt angle α with respect to the horizontal plane of the separating plane satisfies α=45°−(θ/2), where θ is a maximum tilt angle of the display section by the tilt mechanism.
