Abstract
A display device includes a circuit board having a plurality of pixels arranged thereon, each pixel having a plurality of light emitting elements, a driving circuit driving the light emitting elements, a case housing the above, a frame having flanges at a circuit board side of the case to block external light toward the light emitting elements, and a shield disposed between the frame and the case to block electromagnetic noise. A screw is inserted into a through hole and placed into a screw receiving portion to fix the frame and the case. The screw receiving portion has a cylindrical metal portion housing the screw and electrically connecting the screw and the shield, and a resin portion interposed between the placed screw and the inner wall surface of the cylindrical metal portion.
