摘要： PROBLEM TO BE SOLVED: To provide an optical element having an increased viewing angle while having improved luminance by condensing light, to provide a backlight unit and a liquid crystal display having the same. SOLUTION: The optical element includes: a light-transmitting base film; a plurality of diffusion cavities or convex formed on one surface of the base film and diffusing light entering the base film; and a light condensing pattern including a plurality of condensing protrusions formed so as to condense incident light on the one surface of the base film where the diffusion cavities or convex are formed. The backlight unit includes the optical element. The liquid crystal display includes the backlight unit. COPYRIGHT: (C)2010,JPO&INPIT

摘要： The present invention relates to an optical device which maintains luminance characteristics at a maximum level, improves light-collecting effects, and enables a wide viewing angle, and to a backlight unit and a liquid crystal display comprising the same. To this end, one embodiment of the optical device of the present invention includes: a base film having a light transmittance; a plurality of iron portions formed on at least one surface of the base film; and a fine optical pattern containing a plurality of apexes and recesses continuously formed on parts of the iron portions. In the meantime, another embodiment of the optical device of the present invention includes a base film having a light transmittance, and a plurality of third fine optical patterns formed on at least one surface of the base film, wherein each of the third fine optical patterns has a portion contacting the surface of the base film, formed into a figure with a longer axis and a shorter axis, and wherein each of third fine optical patterns has an apex with a height that becomes lower as the latter goes from the center towards both ends thereof according to the direction of the longer axis of the figure.
摘要翻译：本发明涉及将亮度特性保持在最大水平，提高聚光效果并且能够实现宽视角的光学装置，以及背光单元和包括该光学装置的液晶显示器。为此，本发明的光学装置的一个实施例包括：具有透光率的基膜; 形成在所述基膜的至少一个表面上的多个铁部; 以及包含连续形成在铁部分的多个顶点和凹部的精细光学图案。同时，本发明的光学器件的另一实施例包括具有透光率的基膜和形成在基膜的至少一个表面上的多个第三精细光学图案，其中第三精细光学图案具有与基膜的表面接触的部分，其形成为具有较长轴线和较短轴线的图形，并且其中每个第三精细光学图案具有顶点，其高度随着后者从中心朝向两者而变低其端部根据图的长轴方向。
