Abstract
An organic light-emitting display (OLED) panel includes a substrate and a light-emitting pixel array disposed on the substrate and including a plurality of light-emitting pixels, each of the plurality of light-emitting pixels includes a concave structure, a light-emitting layer, a planarization layer, and a convex microlens which are sequentially stacked up and aligned up on the substrate in such a manner that light emitted in an angle perpendicular to the light-emitting layer on the concave structure pass through an focal point of the convex microlens.
