A display device including a display area (DA) and a non-display area (NA) at least partially surrounding the display area (DA), wherein the non-display area (NA) includes a sealing area (SA), the display device comprising: a first substrate including a first base substrate and a light-emitting element disposed on the first base substrate ; a second substrate disposed over the first substrate ; and a sealing member disposed in the sealing area (SA) between the first substrate and the second substrate , wherein the sealing member is not disposed outside the sealing area (SA) wherein the sealing member includes a first linear portion extending in a first direction (X), and a second linear portion extending in a second direction (Y) different from the first direction (X), and characterized in that the first base substrate comprises a main portion having a first maximum width (W 111a ) in the first direction (X) and a protruding portion protruding from the main portion in the second direction (Y) and having a second maximum width (W 111b ) smaller than the first maximum width (W 111a ) in the first direction (X), wherein the sealing member further includes a first curved-portion extending from the first linear portion , and a third linear portion extending in the first direction (X) from the first curved portion , the first linear portion of the sealing member overlaps the protruding portion of the first base substrate , and the third linear portion of the sealing member overlaps the main portion of the first base substrate , wherein the first curved portion includes at least one curved section and a maximum width of the first linear portion (W 311 ) is greater than a maximum width of the second linear portion (W 321 ). a first substrate including a first base substrate and a light-emitting element disposed on the first base substrate ; a second substrate disposed over the first substrate ; and a sealing member disposed in the sealing area (SA) between the first substrate and the second substrate , wherein the sealing member is not disposed outside the sealing area (SA) wherein the sealing member includes a first linear portion extending in a first direction (X), and a second linear portion extending in a second direction (Y) different from the first direction (X), and characterized in that the first base substrate comprises a main portion having a first maximum width (W 111a ) in the first direction (X) and a protruding portion protruding from the main portion in the second direction (Y) and having a second maximum width (W 111b ) smaller than the first maximum width (W 111a ) in the first direction (X), wherein the sealing member further includes a first curved-portion extending from the first linear portion , and a third linear portion extending in the first direction (X) from the first curved portion , the first linear portion of the sealing member overlaps the protruding portion of the first base substrate , and the third linear portion of the sealing member overlaps the main portion of the first base substrate , wherein the first curved portion includes at least one curved section and a maximum width of the first linear portion (W 311 ) is greater than a maximum width of the second linear portion (W 321 ). <EOS>
