Abstract: A wrist watch type flexible display device, or more specifically, a wrist type display device having a flexible display which is rotatable and convertible between bent state and un-bent state, is provided. Accordingly, a wrist watch type display device includes a wrist band, a flexible display, a main body comprising a circuit and an electronic component embedded therein, a rotational engagement member engaged with a lower surface of the flexible display to rotate the flexible display, a flex adjustment member formed on the lower surface of the flexible display to be bent or un-bent, thus causing the flexible display to be interactively bent or un-bent, and a string member embedded in the flex adjustment member to be pulled and released, thus causing the flex adjustment member to be interactively bent or un-bent.
