Display device

A display device comprising:

• a substrate including a first display area, a second display area, which is surrounded by the first display area and includes a light-transmitting part, and a third display area, which is disposed between the first display area and the second display area, wherein the light-transmitting part transmits light therethrough;
• a first subpixel including a first thin-film transistor (TFT), which is disposed on the first display area of the substrate, and a first light-emitting element, which is disposed on the first TFT and is electrically connected to the first TFT;
• a second subpixel including a second TFT, which is disposed on the third display area of the substrate, and a second light-emitting element, which is disposed on the second display area of the substrate and does not overlap with the second TFT in a plan view;
• a thin-film encapsulation layer including a first encapsulation inorganic layer, which is disposed on the first and second subpixels, an encapsulation organic layer, which is disposed on the first encapsulation inorganic layer, and a second encapsulation inorganic layer, which is disposed on the encapsulation organic layer;
• and
• a first transparent conductive layer disposed between the second TFT and the second light-emitting element to electrically connect the second TFT and the second light-emitting element,
• wherein each of the first encapsulation inorganic layer, the encapsulation organic layer, and the second encapsulation inorganic layer has a refractive index of about 1.5 to about 1.7.
