A white organic light emitting diode includes an emission layer that includes a blue emission layer and an emission layer excluding blue. A detector may detect a drawing such as a diagram or chart from ink input by detecting closed containers andor unclosed connectors in the drawing. The first conductive layer includes a first metal layer disposed over the high-k dielectric layer, a second metal layer disposed over the first metal layer, and a third metal layer disposed over the second metal layer. Alternatively, a hydrogel composition is generated in situ in an artery which nourishes a tumor to occlude the artery. In a case where the encoding rate 13<R\u226623, one bit is set. The plurality of pins in each row is the same.
