Flexible display device having flexible display substrate with bending area between display area and peripheral circuit area

A flexible display device comprising:

• a multi-layered substrate structure including:
• a first flexible substrate having at least one display area, and
• a second flexible substrate fixed to the first flexible substrate and more rigid than the first flexible substrate, the second flexible substrate formed with a bending pattern to define a bending area along which the multi-layered substrate structure is bent;
• and
• an organic light emitting element on the first flexible substrate of the multi-layered substrate structure,
• wherein the first flexible substrate comprises a plurality of display areas, and the bending pattern is at a boundary of the at least two adjacent display areas, and the bending pattern is formed with a plurality of holes, a slit extending across the bending area or a half-cut channel.
