A retractable support for a screen, and interior layout assembly for an aircraft cabin comprising such a support are provided. The retractable support for a screen includes a housing for receiving the screen in a retracted position, and an arm movably mounted relatively to the housing between a retracted position inside the housing and a deployed position outside the housing. The arm includes first and second rigid segments jointed with each other so that the second segment pivots relatively to the first segment around a first pivot axis between a compact configuration, in which the second segment is fitted into a recess of the first segment, and an extended configuration, in which the second segment extends out of said recess.
