Abstract
Provided is an organic light-emitting display panel, including: a thin film transistor layer provided in a display area; an organic light-emitting layer provided in the display area and including light-emitting pixels; a microlens array layer provided in the display area and including microlenses corresponding to the light-emitting pixels; a refractive index matching layer provided in the display area; and a filling layer provided in the non-display area. The refractive index matching layer and the microlens array layer have different refractive indexes. Each microlens includes a first surface that is in contact with the refractive index matching layer. 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. A material of the filling layer is same as at least one of materials of the microlens array layer and the refractive index matching layer.
