  • Fixing device for panel member
    Patent number: 10583789
    Abstract: A panel case of a display panel is provided with a first fixing piece extending rearward (in the Y2 direction), and a female threaded hole is formed in the first fixing piece. A support bracket is provided with a second fixing piece extending rearward (in the Y2 direction), and an attachment hole is formed in the second fixing piece. The first fixing piece has a first elongate hole portion opened between the female threaded hole and a first base portion, and the second fixing piece has a second elongate hole portion formed between the attachment hole and a second base portion. Therefore, the fastening force from a fixing screw is less likely to be transmitted to the first base portion of the first fixing piece, and strain of the display panel can be regulated.
