Abstract
An OLED display includes: a thin film transistor including a gate electrode, a source electrode, and a drain electrode; a planarization layer on the thin film transistor and including a contact hole at least partially exposing the drain electrode; a pixel electrode on the planarization layer and coupled to the drain electrode of the thin film transistor through the contact hole; a pixel defining layer on the planarization layer and having an opening that exposes the pixel electrode; an organic emission layer on the pixel electrode; and a common electrode on the organic emission layer and the pixel defining layer. The pixel defining layer includes a corner-cube pattern facing the common electrode.
