Display device

A display device comprising a foldable case unit and a flexible display panel, wherein

• the case unit includes
• an elongated connecting plate,
• a first support member having a tubular shape and coupled to a first one of long sides of the connecting plate via a first hinge part, and
• a second support member having a tubular shape, coupled to a second one of the long sides of the connecting plate via a second hinge part, and having a variable dimension perpendicular to a longitudinal direction of the connecting plate,
• when the case unit is opened to allow the first and second support members to be flush with each other, the first support member, the connecting plate, and the second support member are aligned flush with one another in a direction perpendicular to the longitudinal direction of the connecting plate, and
• when the case unit is folded to allow the first and second support members to face each other, a dimension of the second support member in the direction perpendicular to the longitudinal direction of the connecting plate is larger than a dimension in the opened case unit, and the display panel is accommodated in a space surrounded with the first and second support members and the connecting plate, wherein
• the second support member includes
• a first member coupled to the second one of the long sides of the connecting plate via the second hinge part, and
• a second member coupled to the first member via an elastic member and disposed flush with the first member,
• the dimension of the second support member in the direction perpendicular to the longitudinal direction of the connecting plate is varied in accordance with variation in distance between the first and second members caused by expansion or contraction of the elastic member,
• the first member includes a main portion and an extending portion, the extending portion projecting from a surface of the main portion adjacent to the second member,
• a dimension of the main portion in a Z direction perpendicular to a main surface of the second member is larger than a dimension of the extending portion in the Z direction,
• the second member includes a first member accommodating portion to which the extending portion is inserted,
• a dimension of the first member accommodating portion at an end of the second member is an X direction parallel to a longitudinal direction of the connecting member is not less than a dimension of the extending portion in the X direction, and
• a dimension of the first member accommodating portion in a Y direction perpendicular to the X direction and the Z direction is not less than a dimension of the extending portion in the Y direction.
