The invention discloses a light guide optical fiber total convergence liquid crystal assembled display device. The display device structurally comprises a light guide rear box and protection corners,the protection corners are attached to the outer surface of the light guide rear box. When the light-guide fiber is mounted in the inner opening groove the light-guide fiber firstly abuts against an expanding port; the soft head is stressed; an unfolding and bending layer is unfolded to pull a pull head; the stretching opening connected to the middle part plays a role in manufacturing and counterforce; when the two sides are stressed and extruded, the light-guide fiber is in a tight state and a certain return force is given thereto; when the fixing buckle is clamped, the light-guide fiber is easily in an unfolded state; the light-guide fiber can be pressed open when being installed; when resistance is lost, the light-guide fiber which is timely reset and abuts against the surface of the space limiting layer is stressed together, and when the liquid crystal display equipment is assembled, the internal buckle carries out certain counter-force forward direction on the light guide fiber through swinging force while the light guide fiber needs to be bent, so that the light guide fiber can not be clamped and bent by the fixing buckle, and the light guide effect is not influenced.
