MULTILAYER OPTICAL SHEET MODULE
First Claim
1. A multilayer optical sheet module comprising:
- an upper optical sheet comprising a first structural pattern projected upward;
a lower optical sheet disposed under the upper optical sheet, 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,wherein the second structural pattern comprises,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 a predetermined portion embedded in the adhesion layer, anda circumference of a cross section possessed by the embedded part, contacting 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.
