    • The present invention relates to an optical sheet which includes a base film and a diffuser formed on a surface of the base film. The diffuser includes an anti-adhesion pattern with a plurality of arched protrusions. The bottom of the protrusions is formed to be a closed surface. The side of the protrusions includes a first surface extended from one side of the edge of the bottom and a second surface extended from the other side of the edge of the bottom. An intersection between the first surface and the second surface is formed to be a curve and is extended from one spot on the edge of the bottom to another spot on the edge of the bottom. The optical sheet has excellent anti-adhesion properties and prevents wet-out, Newton′s ring, and moire phenomenon without decreasing luminance.
    • 本发明涉及一种光学片,其包括基膜和形成在基膜表面上的漫射体。 扩散器包括具有多个拱形突起的防粘附图案。 突起的底部形成为封闭表面。 突起的一侧包括从底部的边缘的一侧延伸的第一表面和从底部的边缘的另一侧延伸的第二表面。 第一表面和第二表面之间的交叉点形成为曲线,并且从底部的边缘上的一个点延伸到底部边缘上的另一个点。 该光学片具有优异的防粘附性能,并且防止湿润,牛顿环和莫尔条纹现象而不降低亮度。

    • PURPOSE: A prism sheet, a backlight unit including the same and an optical display device including the same are provided to improve scratch resistance while minimizing the decline of brightness. CONSTITUTION: A prism sheet (10) comprises a base film (100) and a light refraction part (110). The base film has one even side (101). The light refraction part arranges multiple prisms (121, 131), which are having the particular shape of a cross section, integrally with the base film in one direction at the other side of the base film facing the one even side of the base film. The light refraction part comprises a first pattern part (120) having a certain height according to the arranging direction of the prism and a second pattern part (130) in which a height varies according to the arranging direction of the prism. The maximum value of the height of the prism composing the second pattern part is above the height of the prism composing the first pattern part.
    • 目的:提供棱镜片,包括该棱镜片的背光单元和包括该棱镜片的光学显示装置,以在使亮度下降最小化的同时改善耐划伤性。 构成:棱镜片(10)包括基膜(100)和光折射部(110)。 基膜具有一个偶边(101)。 光折射部分将具有特定形状截面的多个棱镜(121,131)在基膜的与基膜的一个偶数侧相对的另一侧沿一个方向与基膜一体地布置。 光折射部包括根据棱镜的排列方向具有一定高度的第一图形部分(120)和高度根据棱镜的排列方向而变化的第二图案部分(130)。 构成第二图案部分的棱镜的高度的最大值高于构成第一图案部分的棱镜的高度。
