Flexible display device

A flexible display device, comprising:

• a display substrate including a display area and a non-display area surrounding the display area, wherein the display area includes an emission element layer;
• an inorganic layer formed over the display substrate in the display area and the non-display area;
• a thin film encapsulation layer formed over the inorganic layer and covering at least a portion of the inorganic layer;
• and
• a plurality of dummy patterns formed over the display substrate and the inorganic layer,
• wherein the dummy patterns comprise:
• a plurality of first dummy patterns formed in the non-display area of the display substrate not overlapping the inorganic layer;
• and
• a plurality of second dummy patterns formed in the non-display area of the display substrate overlapping the inorganic layer,
• wherein the thin film encapsulation layer does not cover any of the first dummy patterns,
• wherein the plurality of first dummy patterns do not overlap the inorganic layer and the thin film encapsulation, and
• the plurality of second dummy patterns overlap the inorganic layer and the thin film encapsulation, and
• wherein the thin film encapsulation layer directly contacts at least one of the second dummy patterns.
