A liquid crystal display apparatus includes a display panel that displays an image, a backlight unit that provides a light to the display panel, and a frame that accommodates the display panel and the backlight unit. The backlight unit includes a light source that emits the light, a diffusion plate that diffuses the light from the light source, an optical sheet that condenses the diffused light and provides the condensed light to the display panel, and a clip that couples the diffusion plate and the optical sheet.
