1. A display device comprising:
- a flexible display substrate; and
a curvature variation device on a rear surface of the flexible display substrate, comprising;
a substrate contact member which is received in a guide recess at the rear surface of the flexible display substrate and contacts the rear surface of the flexible display substrate; and
a length variation member supported by the substrate contact member,whereina length of the length variation member is configured to be varied in response to user input to the curvature variation device,variation of the length of the length variation member in response to the user input to the curvature variation device varies a length of the substrate contact member in the guide recess at the rear surface of the flexible display substrate, andvariation of the length of the substrate contact member in the guide recess at the rear surface of the flexible display substrate varies a curvature of the flexible display substrate.
