Transparent display device

A transparent display device, comprising:

• first and second transparent display panels arranged along a first direction, each of the first and second transparent display panels including:
• a first substrate including a first display area and first to fourth bezel areas surrounding the first display area, wherein the first display area includes a plurality of first pixel regions each including a first emitting portion and a second transparent portion;
• a second substrate facing the first substrate;
• a first transparent dam disposed in the first to fourth bezel areas and between the first and second substrates;
• a first pad electrode disposed on the first substrate and in the first bezel area;
• and
• a first color filter pattern on the second substrate and in the first bezel area;
• and
• third and fourth transparent display panels disposed at a second direction being perpendicular to the first direction with respect to the first and second transparent display panels and arranged along the first direction, each of the third and fourth transparent display panels including:
• a third substrate including a second display area and fifth to eighth bezel areas surrounding the second display area, wherein the second display area includes a second plurality of pixel regions each including a second emitting portion and a second transparent portion;
• a fourth substrate facing the third substrate;
• a second transparent dam disposed in the fifth to eighth bezel areas and between the third and fourth substrates;
• a second pad electrode disposed on the third substrate and in the fifth bezel area;
• and
• a second color filter pattern disposed on the fourth substrate and in the fifth bezel area,
• wherein the first bezel area of the first and second transparent display panels is disposed at a side opposite to the fifth bezel area of the third and fourth transparent display panels.
