DISPLAY DEVICE ALLOWING REPEATED REMOVAL AND INSTALLATION OF SCREW
First Claim
1. A display device comprising:
- a circuit board having a pixel formed by a plurality of light emitting elements arranged thereon;
a driving circuit for driving the light emitting elements,a case to which the circuit board and the driving circuit are to be arranged,a frame disposed at a circuit board side of the case and having a flange to block external light from entering the light emitting elements, the frame being defining a through hole through which a screw can be inserted;
a shield disposed between the frame and the case to block electromagnetic noise; and
a screw inserted through the through hole defined in the frame,wherein a screw receiving portion is provided in the case, the screw inserted through the through hole in the frame is placed into the screw receiving portion provided in the case to fix the frame with the case, andwherein the screw receiving portion has a cylindrical metal portion to house the screw and to electrically connect the screw to the shield and a resin portion interposed between the placed screw and an inner wall of the cylindrical metal portion.

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.
