Document Type and Number:
WIPO Patent Application WO/2010/038516
Kind Code:
A1
Abstract:
A first reflection sheet (3) is arranged on the side opposite to surfaces having outgoing surfaces (5c) of light guide bodies (5) to individually cover the surfaces on the opposite side. A second reflection sheet (4) is arranged on the side opposite to the surfaces on the side of the light guide bodies (5) of the first reflection sheet (3), between the light guide bodies (5) to cover a region where the first reflection sheet (3) does not exist, in a first gap (1) formed at a part where the adjacent two light guide bodies (5) are continuous without overlapping with each other. Thus, an illuminating device (31), which is thin and has further improved luminance uniformity on a light emitting surface is provided by individually arranging the first reflection sheet (3) for the light guide bodies (5), even the gap (1) is formed between the light guide bodies (5).
