The present disclosure provides a frame component and a display device. The frame component comprises a glue frame and a backboard. The glue frame comprises a glue frame sidewall which encloses as a frame-type structure. The backboard comprises a backboard sidewall and a backboard bottom wall. The backboard sidewall surrounds the external side of the glue frame sidewall. The glue frame sidewall is provided with a fixing structure for connecting the glue frame to the backboard in a fixed manner, and the fixing structure forms a defining structure at the lower surface of the backboard bottom wall. The defining structure is used for defining the position of the printed circuit board. The present disclosure can simplify the structures of the frame component and the display device.
