    摘要： A light guide plate includes a first optical member having a first light path-changing portion to separate a first light portion and a second light portion from a light, and a second optical member having a second light path-changing portion corresponding to the first light path-changing portion. The first optical member has a first refractive index against the first light portion of the light and a second refractive index against the second light portion of the light, and the second optical member has the first refractive index against the first and second light portions. Thus, brightness and brightness uniformity of an image displayed on a display apparatus may be improved, and a number of parts of the display apparatus may be reduced.

    摘要： An optical member that lends itself to be more cost-effectively manufactured than a conventional optical member is presented. A display device made with the optical member can be thinner than the conventional optical member. The optical member includes a light-incident face that receives light emitted from a lamp positioned at a side of the optical member, a light-exiting face that is in a plane perpendicular to the light-incident face, and a light reflecting face opposite to the light-exiting face. A light-concentrating pattern having a plurality of concentric circles is formed on the light-exiting face. The light-concentrating pattern may be the Fresnel lens pattern. A diffusing pattern for diffusing the light is formed on the light reflecting face. Since patterns are formed on the optical member, additional optical sheet such as a prism sheet, a reflective polarizing sheet, a diffusion sheet, etc., is unnecessary.

    摘要翻译： 本发明提出一种光学元件，它比传统光学元件更经济高效地制造。 由光学构件制成的显示装置可以比传统的光学构件更薄。 光学构件包括光入射面，其接收从位于光学构件侧的灯发出的光，与光入射面垂直的平面中的光出射面和与光入射面相反的光反射面 光出面。 在出射面上形成具有多个同心圆的聚光图案。 光聚集图案可以是菲涅尔透镜图案。 在光反射面上形成用于漫射光的扩散图案。 由于在光学构件上形成图案，所以不需要诸如棱镜片，反射偏振片，扩散片等附加的光学片。
