Display device

A display device, comprising:

• a substrate that includes a first substrate, a first inorganic layer, a second substrate, and a second inorganic layer, which are sequentially stacked;
• a circuit layer on the substrate;
• a display element on the circuit layer;
• at least one hole penetrates the substrate;
• a first groove and a second groove surround the at least one hole, and
• an encapsulation layer that covers the display element,
• wherein the second groove is spaced apart from and surrounds the first groove, and
• the encapsulation layer comprises an organic encapsulation layer that fills the second groove.
