Abstract: Disclosed is a display device including a display panel including a first non-folding region, a folding region, and a second non-folding region sequentially disposed in a first direction, a support plate disposed below the display panel and including openings that overlap the folding region in a plan view, and an impact resistance enhancement layer disposed below the display panel. The support plate has a groove that overlaps the folding region in a plan view. The impact resistance enhancement layer is disposed in the groove of the support plate and has a modulus in a range of about 3 GPa to about 6 GPa.

Abstract: A display device includes a display module, first and second bodies disposed below the display module and arranged in a first direction in an unfolded state, a hinge which is disposed between the first and second bodies and in which first and second rotary axes extending parallel to each other in a second direction intersecting the first direction are defined, and a hinge bar coupled to the hinge and extending in the second direction. The first and second bodies may rotate around the first and second rotary axes, respectively, to be in an in-folded state in which front surfaces of the first and second bodies face each other, or in an out-folded state in which rear surfaces of the first and second bodies face each other. A distance between the first and second rotary axes and the hinge bar in the unfolded is different than in in-folded states.

Abstract: An electronic device includes a display module including a first non-folding portion, a first folding portion, a second non-folding portion, a second folding portion, and a third non-folding portion. The electronic device further includes a first plate disposed under the display module and including first openings overlapping the first folding portion and second openings, a second plate including a first substrate, a second substrate, and a third substrate, an adhesive layer disposed between the first plate and the second plate and including a first portion overlapping the first folding portion and a second portion spaced apart from the first portion, and a plurality of sticks disposed between the second substrate and the third substrate and spaced apart from each other in the first direction. A portion of the second portion overlapping the second folding portion is exposed through spaces between the sticks.

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.
