Abstract:
An embodiment of the present invention reduces difference in brightness between a portion where a tab of an optical sheet is formed and a portion where the tab is not formed. A frame ( 3 ) of a planar light source device ( 1 ) has an inclined surface ( 13 ) formed so as to incline with respect to a direction perpendicular to a light exit plane and to face in a direction opposite to the light exit plane. The inclined surface ( 13 ) is formed at least at a portion where a cut part ( 17 ) is not formed, which portion is part of a surface ( 12 ) of the frame ( 3 ) which surface ( 12 ) faces a lateral surface ( 11 ) of a light guide plate ( 2 ). At a bottom surface ( 14 ) of the frame ( 3 ), a light absorbing member ( 6 ) is provided.

Claim (Index 4):
The planar light source device as set forth in  claim 3 , wherein:\n in a cross section of the frame along a vertical direction, a width of the first inclined surface is not less than half a width of the protruding bottom portion.
