Abstract: A backlight unit includes a bottom cover, a light source, a middle mold, a diffusion plate and an optical sheet. The bottom cover defines a bottom portion and a sidewall portion which is protruded from the bottom portion. The light source is accommodated in the bottom cover. The middle mold is supported by the bottom cover and defines a horizontal supporting portion and a distance maintaining portion extending from a first end of the horizontal supporting portion in a direction perpendicular to the bottom portion. The diffusion plate overlaps the horizontal supporting portion. The optical sheet overlaps the distance maintaining portion and is spaced apart from the diffusion plate.

Abstract: A display device includes first and second sidewall portions and a display module disposed therebetween that is folded with respect to an axis. A moving portion is connected to a first side of the display module and is disposed between the first sidewall portion and the second sidewall portion in a non-expanded mode. A link portion is connected to a second side of the display module. A driving integrated circuit is disposed below the display module and includes a heat discharge plate disposed thereon. The moving portion is configured to move in the first direction to bring the display device into an expansion mode in which the moving portion is farther displaced from the second side of the display module and the link portion is configured to expand in the first direction so that a portion of the link portion overlaps with the heat discharge plate.
