Abstract:
A light emitting structure includes a first hole injection layer, a first organic light emitting layer, a charge generation layer, a second hole injection layer, a second organic light emitting layer, an electron transfer layer, and a blocking member. The light emitting structure has first, second, and third sub-pixel regions. The first organic light emitting layer may be on the first hole injection layer. The charge generation layer may be on the first organic light emitting layer. The second hole injection layer may be on the charge generation layer. The second organic light emitting layer may be on the second hole injection layer. The electron transfer layer may be on the second organic light emitting layer. The blocking member may be at at least one of the first to the third sub-pixel regions.
