Abstract
A liquid crystal display device thermally insulated from light source heat, includes a display panel, a backlight module positioned on the display panel, a bezel positioned around the backlight module, and a thermal insulating element mounted on the bezel. The backlight module includes a light guiding plate and at least one light source located at a side of the light guiding plate. The thermal insulating element is positioned between the at least one light source and the bezel. A sealed space is formed between the thermal insulating element and the bezel. The thermal insulating element and the sealed vacuum space are configured to thermally insulate heat generated by the at least one light source and prevent heat from transferring to the bezel and display panel.
