LIGHT EMITTING DEVICE PACKAGE, BACKLIGHT UNIT, LIGHTING DEVICE AND ITS MANUFACTURING METHOD

摘要

The present invention relates to a light emitting device package used for display or lighting, a backlight unit, a lighting device and its manufacturing method. The light emitting device package may include: a substrate core layer made of a thermal conductivity material; a substrate insulating layer which surrounds the substrate core layer and is made of an insulating mixture where binder and heat radiating powder are mixed; an upper electrode layer which is formed on the upper side of the substrate insulating layer and comprises a first electrode layer and a second insulating layer with an electrode separation space; a lower electrode layer formed on the lower side of the substrate insulating layer; and a lateral electrode layer which is formed on the lateral side of the substrate insulating layer and electrically connects the upper electrode layer and the lower electrode.
