A flat display device includes a display panel, a frame which holds the display panel, and a frame-shaped bezel which is fixed to the frame and holds the display panel on the frame. The bezel has a surface portion, side face portion, reverse portion, fixed portion, and stress easing portion. The surface portion has an end side on the boundary with a display region of the display panel and covers a first main surface of the display panel with the display region exposed. The side face portion covers at least a part of a side face of the frame. The reverse portion extends covering at least a part of a reverse surface of the frame. The fixed portion is provided on the reverse portion and fixed to the frame. The stress easing portion is situated near a shortest path extending from the fixed portion of the bezel toward the end side and eases stress in a direction such that the surface portion and the display panel are separated from each other.
