Appeal No. 1999-2713 Page 3
Application No. 08/801,805
BACKGROUND
Appellants' invention relates to a side light type
surface light source. A roughness is applied to the emitter
surface 12 of light scattering guide plate 11 to prevent the
sheet-shaped light control member 5 from adhering to the
emitting surface, without loss of directivity. An
understanding of the invention can be derived from a reading
of exemplary claim 7, which is reproduced as follows:
7. A side light type surface light source device
comprising:
a sheet-shaped light control member disposed closely
along an emitting surface emitting light having directivity
and functioning to correct directivity of the emitted light;
wherein a roughness is applied to the emitting surface to
prevent the light control member from adhering to the emitting
surface without losing the directivity of light emitted from
the emitting surface.
