An organic light emitting display device may include a substrate including a display area and a non-display area; a thin film transistor on the substrate in the display area; a planarization layer covering the thin film transistor; a first electrode on the planarization layer in the display area and connected to the thin film transistor; a pixel defining layer covering the first electrode and including a first opening that exposes a portion of the first electrode to define an emission area; a first light blocking layer on the pixel defining layer and including a photochromic material, a color of the first light blocking layer being reversibly changed by ultraviolet light; an organic light emitting layer on the first electrode; and a second electrode on the organic light emitting layer.

Organic light emitting display device and method of manufacturing the same

Disclosed is a method of fabricating a thin film solar cell including introducing a reaction solution into a reaction chamber, fixing a supporter onto a loader, disposing the loader in the reaction chamber to immerse the supporter into the reaction solution, and heating the supporter and coating a buffer layer. In addition, an apparatus of fabricating a thin film solar cell including a reaction chamber mounted with an inlet of a reaction solution and an outlet of waste water, and a loader disposed in the reaction chamber and being capable of moving up and down, is disclosed.
