PURPOSE:To provide the manual turning display device constituted in such a manner that the entire part of the device can be repetitively rotated by a simple operation in the state of directing the surface of a light emitting cell array toward a specified direction and that a prescribed image can be stably displayed within the plane of rotation even if the fluctuation in the speed of the rotation is large. CONSTITUTION:This manual turning display device has a device body 1 which is arranged linearly with the many light emitting cells 3 in its surface part along a longitudinal direction in the form of a slender and nearly bar form, an operating fulcrum member 4 which is freely rotatable around the axial line in the direction orthogonal with the longitudinal direction of this device body 1, a rotation detecting means which obtains the relative rotating position information and rotating speed information of the operating fulcrum member 4 with respect to the device body 1 by detecting the marks of rotating markers, a storage means which stores the image data to be displayed and a display control means which successively reads out the image data from the storage means in synchronization with the detection signals by this rotation detecting means and drives the light emitting cell array 2 according to the image data.
