Organic light-emitting display panel and display apparatus

An organic light-emitting display apparatus, comprising an organic light-emitting display panel,

• wherein the organic light-emitting display panel has a display area and a non-display area surrounding the display area, and the organic light-emitting display panel comprises:
• a thin film transistor layer provided in the display area;
• an organic light-emitting layer provided in the display area and located at a side of the thin film transistor layer close to a light-exiting surface of the organic light-emitting display panel;
• a microlens array layer provided in the display area and located at a side of the organic light-emitting layer close to the light-exiting surface of the organic light-emitting display panel;
• a refractive index matching layer provided in the display area and located at a side of the microlens array layer close to the light-exiting surface of the organic light-emitting display panel;
• and
• at least one filling layer provided in the non-display area,
• wherein the organic light-emitting layer comprises a plurality of light-emitting pixels, the microlens array layer comprises a plurality of microlenses corresponding to the plurality of light-emitting pixels;
• the refractive index matching layer and the microlens array layer have different refractive indexes, each of the plurality of microlenses comprises a first surface that is in contact with the refractive index matching layer, and the first surface is a curved surface protruding towards one of the microlens array layer and the refractive index matching layer which has a smaller refractive index,
• the thin film transistor layer comprises a plurality of inorganic layers extending from the display area to the non-display area, and the at least one filling layer is arranged at a side of the plurality of inorganic layers close to the light-exiting surface of the organic light-emitting display panel, and
• a material of each of the at least one filling layer is same as at least one of a material of the microlens array layer and a material of the refractive index matching layer.
