Display apparatus

A display apparatus comprising:

• a substrate comprising a display area and a non-display area;
• a display layer comprising a first display element and a second display element arranged in the display area;
• and
• a thin-film encapsulation layer arranged to cover the display layer and comprising a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer,
• wherein a refractive index of the organic encapsulation layer is less than refractive indices of the first inorganic encapsulation layer and the second inorganic encapsulation layer,
• a thickness of the organic encapsulation layer is about 3 μm to about 15 μm,
• the refractive index of the first inorganic encapsulation layer is about 1.55 to about 1.85, and
• a first thickness of a first portion of the second inorganic encapsulation layer corresponding to the first display element is different from a second thickness of a second portion of the second inorganic encapsulation layer corresponding to the second display element.
