Abstract

A flexible display component and a display screen are provided. The flexible display component includes a display module; a buffering layer; and at least two fixing parts disposed at the display module for fixing the buffering layer to be movably fixed to a side of the display module, wherein, when the display module is under a natural status, the buffering layer is contacted with the display module, when the display module is under a bending status, a gap layer is existed between the buffering layer and the display module. Through above way, the present invention can improve the bending reliability of the display module.

Claims
