<P>PROBLEM TO BE SOLVED: To provide a multilayer optical sheet module in which a second structural pattern includes a light transmitting part having a traverse cross section getting smaller along an upward direction, and an embedded part continuously connected to an upper portion of the light transmitting part, with at least a portion embedded in the adhesion layer, where a circumference of a cross section at which the embedded part is in contact with the adhesion layer is larger than a circumference of a virtual cross section locus formed by extending the light transmitting part upward with a continuous slope. <P>SOLUTION: There is disclosed a multilayer optical sheet module including: an upper optical sheet comprising a first structural pattern projected upward; a lower optical sheet disposed under the upper optical sheet in a laminated configuration, the lower optical sheet comprising a second structural pattern projected toward the upper optical sheet; and an adhesion layer provided between the upper optical sheet and the lower optical sheet. <P>COPYRIGHT: (C)2013,JPO&INPIT |
