EL DEVICE, PROCESS FOR MANUFACTIURING THE SAME, AND LIQUID CRYSTAL DISPLAY EMPLOYING EL DEVICE

WIPO Patent Application WO/2004/112442

A1

An external light L1 impinging on the transparent substrate (9) of an organic EL device and passing through the substrate (9) further passes through a transparent electrode (10) and an organic light emitting layer (12) before being reflected off a reflective electrode (13). Since the reflective electrode (13) has protrusions and recesses, the external light L1 is scattered thereat and reflected at various angles. When passing through the protruding and recessed surface (11) of the transparent electrode (10), these reflected lights are scattered furthermore and exits from the transparent substrate (9) toward a liquid crystal panel. On the other hand, lights L2-L4 emitted from the organic light emitting layer (12) are scattered when they pass through the protruding and recessed surface (11) of the transparent electrode (10), and exits from the transparent substrate (9) toward the liquid crystal panel.
