Claims

[Scope of utility model registration request]

In a shader device that is installed in front of a large video display device in which a large number of light source tubes are arranged in parallel vertically and horizontally and prevents sunlight from directly hitting the light source tubes, the front surface of each of the light source tubes is not obstructed. A large number of shaders whose back surfaces are connected by supporting pieces, and a mounting plate that protrudes from the back side of the supporting pieces and has the large number of light source tubes arranged in parallel, are deformed when passing through the hole, and then restored and engaged with the edge of the hole. A shader device for a large-sized video display device, characterized in that it is equipped with an elastic engagement claw.
