A display apparatus includes a first roller and a second roller each rolling about a rolling axis extending along a first direction and spaced apart from each other in a second direction crossing the first direction, a display panel connected to the first roller, and a support connected to the second roller and disposed on a rear surface of the display panel to support the display panel. A hole passing through the support is defined in the support, the support includes an end part surrounding a portion of the hole and extending along the first direction and a side part extending along the second direction from the end part, and the end part is convex toward the display panel in a cross section.

Display apparatus

A display apparatus includes a display panel rollable around a rolling axis extending in a first direction and a support member disposed below the display panel. The support member includes a base part, support bars each extending in the first direction, arranged in a second direction crossing the first direction, and coupled to the base part, and a protruding part including a first support portion and a second support portion, each of which is disposed below the base part and extends in the second direction. The first support portion overlaps at least a portion of first ends of the support bars, and the second support portion overlaps at least a portion of second ends of the support bars, which are spaced apart from the first ends in the first direction.

Display apparatus and electronic apparatus including the same

A display apparatus includes: a display panel; a first pattern layer on one surface of the display panel; and a second pattern layer facing the one surface with the first pattern layer interposed therebetween, wherein: the first pattern layer comprises a plurality of first patterns each having a closed line shape comprising a first opening; the second pattern layer comprises a plurality of second patterns each having a closed line shape comprising a second opening; on the one surface, each of the first pattern layer and the second pattern layer has a deformation rate which is smaller in a direction perpendicular to a tensile direction than in the tensile direction; and on the one surface, the first openings overlap portions of the second patterns.

A display module including a display unit and a support member disposed below the display unit and including first areas and second areas. The support member includes a matrix, a first supporter disposed in the matrix and including first extension parts, each extending in a first direction and spaced apart from each other in a second direction crossing the first direction, and a second supporter disposed in the matrix and including second extension parts, each extending in the first direction and spaced apart from each other in the second direction, and connection parts disposed between the second extension parts, where the second extension parts and the connection parts define openings in the second supporter.

Rollable display device

A display device includes a housing, a display module, a support film, and a frame. The display module is accommodated in the housing in a first state and unrolled from the housing to a first direction in a second state. The support film is accommodated in the housing in the first state and unrolled from the housing to the first direction in the second state to support the display module. The frame shrinks to a first shape in the first state and expands to a second shape in the second state in a way such that the frame applies a tensile stress to the support film in the second state.
