The wiring pattern is connected to the control means via a rotation member.

  Here, in a fan-shaped display device that opens and closes a plurality of strip-shaped members in a fan shape, the wiring pattern is connected to the control means via a rotation member. For this reason, even if a display element is provided for each of the plurality of strip-shaped members, it is possible to prevent complication of the wiring pattern extending from the display element provided on each strip-shaped member.

  In this configuration, the plurality of strip-shaped members may be formed in a shape that can be separated from each other in the rotation direction. Thereby, even when each strip-shaped member is formed in a shape separable with respect to the rotation direction, each strip-shaped member can be rotated via the rotation member.

  In addition, when the assembly is opened in a fan shape, the display area formed by all the display elements may be set to be rectangular. Thereby, when a plurality of strip-shaped members are opened in a sector shape, a rectangular display region can be formed by each display element.

  The display element may be formed of organic EL. Thereby, an image can be displayed by the organic EL.

  According to the present invention, when the display elements are separately provided on the plurality of strip-shaped members, an increase in manufacturing cost can be suppressed.
