Flat electrode, ultra thin surface light source device and backlight unit having the same

摘要

There is provided a flat electrode for a surface light source, in which a conductive electrode is formed in a fine strip-shaped pattern on a plane. The flat electrode may comprise a base layer, an electrode pattern formed on the base layer, and a protection layer formed on the electrode pattern. There is also provided an ultra thin surface light source device which comprises: a first substrate and a second substrate which are spaced apart from each other at a predetermined interval; and a first surface electrode formed on the first substrate, and a second surface electrode formed on the second substrate. The surface light source device may further comprise a medium layer formed in at least one of spaces between the first substrate and the first surface electrode and between the second substrate and the second surface electrode.
