  • Patent number: 8384838
    Abstract: A liquid crystal display device is provided, capable of minimizing deterioration in display quality of a liquid crystal panel due to external force generated by connection with an external chassis such as a customer's chassis. The liquid crystal display device has, at least, a front frame, a liquid crystal panel, and a backlight unit having at least a rear frame, arranged in this order. A back fixing frame to be fixed to the front frame is provided on the back face of the liquid crystal display device, and attachment portions to be attached to an external chassis are provided in the back fixing frame. This makes it difficult for external force generated by connection with the external chassis to be transmitted to the liquid crystal panel or the backlight unit, suppresses deformation of the liquid crystal panel or reflection sheet and prevents deterioration in display quality.
