Provided is a light emitting material in which: a light emitting layer
comprising a columnar part of which a cross-sectional shape is column
such as cylindrical column, and a light emitting part of which a
cross-sectional shape is cone or pyramid; and light generated in the
light emitting part is extracted outside through the columnar part. The
light emitting material allows light to be efficiently extracted to the
outside to improve luminance.
