[0047] At present, most flat-panel TVs mainly use stamped steel back panels to support the internal display optical components, and the electronic components are on the outside of the back panel, covered with parts such as the back shell. The back panel is C-shaped bent on the top side and the left and right sides, and the ground side is folded outward, so there are crack stop grooves on the left and right corners of the ground side of the back panel, and the left and right directions are perpendicular to the stamping direction, so it is impossible to achieve precise size control, and the front and rear shells cannot be precisely positioned and designed, so that the assembly surface needs to have an assembly gap, causing the light inside the TV to penetrate from the opening of the back panel along the assembly gap of the front and rear shells, affecting the overall look of the TV. The present application provides a display device to solve the above technical problems.
