A flexible display apparatus, which belongs to the field of display devices. The flexible display apparatus comprises a shear fork frame (100), a housing (200), a reel (300), a flexible display screen (400), and a limiting mechanism (500), wherein the support frame (100) comprises a scissor rack (110); the housing (200) comprises a first portion (210) and a second portion (220), the first portion (210) is located at one end of the shear fork frame (110), and the second portion (220) is located at the other end of the shear fork frame (110); and the limiting mechanism (500) is connected to the shear fork frame (110), and at least one among the first portion (210) and the second portion (220) is provided with the limiting mechanism (500), so as to limit the relative movement of the portion where the limiting mechanism (500) is disposed with respect to the axis of the shear fork frame (110). During the process of expanding the flexible display screen (400) by pulling the first portion (210) and the second portion (220) or extending the flexible display screen (400) by folding the first portion (210) and the second portion (220), the limiting mechanism (500) can limit the relative movement of the portion where the limiting mechanism (500) is located with respect to the axis of the shear fork frame (110), which prevents the flexible display screen (400) from becoming askew in the plane where the shear fork frame (110) is located, and facilitating prevention of extending dislocation of the flexible display screen (400).
