Display device including crack dam arrangement area

A display device, comprising:

• a base substrate comprising an active area, and a non-active area around the active area, the non-active area comprising a crack dam arrangement area;
• a plurality of inorganic layers on the base substrate;
• and
• an encapsulation layer on the plurality of inorganic layers, and comprising an encapsulation inorganic layer, and an encapsulation organic layer on the encapsulation inorganic layer,
• wherein:
• the base substrate comprises first substrate portions having a first thickness at the crack dam arrangement area, and a second substrate portion between adjacent ones of the first substrate portions and connected to the first substrate portions, the second substrate portion having a second thickness smaller than the first thickness;
• the second substrate portion exposes an upper end of a side surface of the first substrate portion adjacent thereto;
• the second substrate portion comprises a first sub-substrate portion and a second sub-substrate portion spaced from each other, and having different widths from each other;
• the plurality of inorganic layers are laminated to form an inorganic laminated film at the crack dam arrangement area;
• a plurality of inorganic laminated films are arranged for each of the first substrate portions, and are spaced from each other with the second substrate portion therebetween;
• the encapsulation inorganic layer comprises the inorganic laminated film, a first encapsulation inorganic layer on the base substrate, and a second encapsulation inorganic layer on the first encapsulation inorganic layer;
• each of the first encapsulation inorganic layer and the second encapsulation inorganic layer is located over the first substrate portions and the second substrate portion, and comprises at least one disconnected portion;
• and
• a thickness of the first encapsulation inorganic layer at the first sub-substrate portion is different from a thickness of the first encapsulation inorganic layer at the second sub-substrate portion.
