Abstract:
1. An organic electroluminescence (EL) display device, comprising: a substrate; a reflection layer arranged on the substrate and including an opening; a first electrode arranged on the reflection layer and in the opening, the opening corresponding to a central portion of the first electrode; a pixel defining layer for exposing a part of the first electrode; an organic layer arranged on the exposed part of the first electrode and comprising at least an organic light-emitting layer; and a second electrode arranged on the organic layer, wherein the first electrode is a transparent electrode, and wherein the organic EL display device emits light in a first direction substantially along the exposed part of the first electrode and emits light in a second direction substantially from only the central portion of the first electrode, the central portion of the first electrode being smaller than the exposed part of the first electrode.
